Objective: to analyze complications and clinical outcome of Camey-Le Duck ureteral reimplantation technique in modified Mainz pouch II urinary diversion. Patients and methods: this retrospective study included a total of 110 patients (101 male and 9 female, mean age 59,2 years, SD=10,2), who had underwent a modified Mainz pouch II urinary diversion with Camey-Le Duck ureteral reimplantation technique, following total cystectomy, during the period 1995-2014. The mean follow-up, available for 90 (82%) patients period was 19 (1-74) months. Early and late postoperative complications were analyzed. Results: early complications developed in 22 (20%) patients as follow: unilateral ureterohydronephrosis in 8 (7%) patients, bilateral ureterohydronephrosis in one (1%)- two RU (renoureteral units), urinary leakage in 8 (7%), and pyelonephritis in 5 (5%) patients. Late complications developed in 28 (25%) patients: pyelonephritis in 17 (15%), and ureteral reimplantation site stenosis in 11 (10%) patients with 12 RU. Balloon dilatation procedure was applied in all 12 RU, with additional metallic Strecker stent insertion in 5 RU. At 24-month follow-up, all patients with metallic Strecker stent had normal results of serum biochemistry, blood gas analysis and renal ultrasound. In the rest of six patients with 7RU, balloon dilatation has failed and restenosis of ureteral reimplantation site with consequent ipsilateral hydronephrosis was verified. In these patients, permanent percutaneous nephrostomy catheter was applied. Conclusion: Camey-Le Duck ureteral reimplantation technique following Mainz pouch II urinary diversion is simple, reliable and durable. It enables well upper urinary tract protection and is associated with relatively low major complication rates.

Abstract Background We report our experience of treating anastomotic strictures using a novel type of fully covered metal stent (FCSEMS). This stent, known as the Kaffes Stent, is short-length with an antimigration waist and is easily removable due to long retrieval wires deployed within the duodenum. Methods Sixty-two patients underwent ERCP and Kaffes stent insertion for post-transplant anastomotic strictures following confirmation of a stricture on MRCP. These patients were retrospectively analysed for immediate and long-term stricture resolution, improvement in symptoms and liver function tests (LFTs), stricture recurrence and complication rates. Results Of the 56 patients who had their stent removed at the time of analysis, 54 (96%) had immediate stricture resolution and 42 continued to have long-term resolution (mean follow-up period was 548 days). Of the 16 patients with symptoms of biliary obstruction, 13 had resolution of their symptoms. Overall, there was a significant improvement in LFTs after stent removal compared to before stent insertion. Complication rates were 15% with only one patient requiring biliary reconstruction. Conclusions The Kaffes stent is effective and safe at resolving post liver transplant biliary anastomotic strictures.

Objectives:Creating a continent urinary pouch has become an alternative to the ileal conduit for patients undergoing exenteration for advanced gynecologic malignancies. The objective of this study was to compare clinical outcomes for the 2 methods.Methods:In this retrospective study, we compared intraoperative and postoperative complications and quality-of-life scores for the modified ileocecal pouch and the ileal conduit in anterior or total pelvic exenteration.Results:In 33 of 100 patients, an ileal pouch (IP) was created; the other 67 were treated by an ileal conduit (IC). Creating an IP prolonged the exenterative procedure by 97 minutes compared to an IC (IC, 453 minutes vs IP, 550 minutes;P= 0.009). Overall complication rates were similar, but patients with an IP had significantly more complications of urinary diversion (48%) than patients with an IC (31%;P= 0.03). Follow-up showed urinary loss and frequency of micturition to be comparable, but in patients with an IP, surgery for stomal complications (n = 2) and treatment of bladderstones were necessary more frequently (n = 3). Quality of life according to the 12-item Short Form Health Survey questionnaire was similar in both groups.Conclusion:A continent IP is an alternative to the IC in cases of pelvic exenteration. Early complications are more frequent with an IP than with an IC. The mode of urinary diversion has little influence on the quality of life in patients with advanced genital cancer.

Objective: To analyze the outcome of Mainz Pouch II urinary diversion related to complications and life quality. Patients and Methods: From 1995 to 2006, a total of 67 patients (60 male and 7 female, mean age 58.4 years, range 48 to 70) who underwent modified ureterosigmoidostomy (Mainz Pouch II) procedure have been retrospectively analyzed. The mean follow-up was 18 (1 - 72) months and it was available for 56 patients (84%). Early and late postoperative complications as well as quality of life after surgery were analyzed. An clinical questionairre has been used for examination specific urinary diversion items. Results: Early postoperative complications (<30 days) we-re detected in 9 patients (13%) and late complications (>30 days) in 19 patients (28%). Early complications consisted of urine leakage of moderate degree in 5 (7%) and ileus requiring surgical revision in 4 (6%) patients. The late complications included acute pyelonephritis in 12 patients (18%) and uretero-sigmoidal anastomotic site stenosis in 7 (11%). Ureterosigmoidal anastomotic site stenosis was detected in 7 patients with 7 renoureteric units (RU). In 4 RU, metal Strecker stent was successfully applied. In 3 RU, permanent nephrostomy catheter was applied. Oral alkalizing agents were applied in 22 patients (33%) due to metabolic acidosis. Two patients died due to severe acidosis. Continent rate was 96%. The mean voiding frequency during the day and night was 5.2+1.8 and 2.7+ 0.5, respectively. Global life quality was bad for 3 (8%), acceptable for 15 (38%) and good for 22 (54%) patients. Conclusion: The Mainz Pouch II urinary diversion is simple and safe procedure regarding complications rate, continence and quality of life. It is good alternative to other forms of continent urinary diversion. Patient selection and compliance following by meticulous follow-up are of utmost importance for successful operative outcome.

The results including the complication and continence rates for 3 types of continent urinary diversion were evaluated. From 1992 to 1998 we performed 58 continent urinary diversions after radical cystectomy for invasive transitional cell carcinoma (TCC) of the urinary bladder. All three types of continent diversions and ileal loop procedures were discussed and patient preferences were determined. The patient preference rate for continent urinary diversion was 96.6%, and half of these patients wanted to be completely dry. Mean age of the patients was 58.2 years. Of the 58 patients, 9 (15.5%) had a Kock pouch, 15 (25.8%) had a Kock neobladder and 34 (58.6%) had sigmoidorectal pouch (Mainz-II pouch). Early and late complication rates of the three different continent diversions were evaluated. The number of complications, such as urine leakage, pyelonephritis, hydronephrosis, reflux and stone formation, were similar in all three types of diversions. Two (5.9%) Mainz pouch II patients who had stopped oral alkalinization demonstrated severe hyperchloremic acidosis. Spontaneous pouch rupture occurred in 1 of the Kock pouches. Reoperation rates were higher with the Kock pouch and Kock neobladder cases. Daytime continence rates for the Kock pouch, Kock neobladder and Mainz II pouch were 77.7%, 86.7% and 100% respectively. Even though complete dryness may not be achieved in every patient, orthotopic bladder substitution appears to be the best choice after radical cystectomy. Although it carries the risk of life-long oral alkalinization therapy, the Mainz pouch II is associated with an excellent continence rate and may be a good alternative for patients who desire to be dry.

Abstract BACKGROUND Operative treatment of adult spinal deformity (ASD) can be very challenging with high complication rates. It is well established that patients benefit from such treatment; however, the surgical outcomes for patients with severe sagittal deformity have not been reported. OBJECTIVE To report the outcomes of patients undergoing surgical correction for severe sagittal deformity. METHODS Retrospective review of a prospective, multicenter ASD database. Inclusion criteria: operative patients age ≥18, sagittal vertical axis (SVA) ≥15 cm, mismatch between pelvic incidence and lumbar lordosis (PI-LL) ≥30°, and/or lumbar kyphosis ≥5° with minimum 2 yr follow-up. Health-related quality of life (HRQOL) scores including minimal clinically important difference (MCID)/substantial clinical benefit (SCB), sagittal and coronal radiographic values, demographic, frailty, surgical, and complication data were collected. Comparisons between 2 yr postoperative and baseline HRQOL/radiographic data were made. P &lt; .05 was significant. RESULTS A total of 138 patients were included from 502 operative patients (54.3% Female, Average (Avg) age 63.3 ± 11.5 yr). Avg operating room (OR) time 386.2 ± 136.5 min, estimated blood loss (EBL) 1829.8 ± 1474.6 cc. A total of 71(51.4%) had prior fusion. A total of 89.9% were posterior fusion only. Mean posterior levels fused 11.5 ± 4.1. A total of 44.9% had a 3-column osteotomy. All 2 yr postoperative radiographic parameters were significantly improved compared to baseline (P &lt; .001 for all). All 2yr HRQOL measures were significantly improved compared to baseline (P &lt; .004 for all). A total of 46.6% to 73.8% of patients met either MCID/SCB for all HRQOL. A total of 74.6% of patients had at least 1 complication, 11.6% had 4 or more complications, 33.3% had minimum 1 major complication, and 42(30.4%) had a postop revision. CONCLUSION Patients with severe sagittal malalignment benefit from surgical correction at 2 yr postoperative both radiographically and clinically despite having a high complication rate.

Background: Limited intermediate and no real long-term follow-up data have been published for total ankle arthroplasty (TAA) in the United States. This is a report of clinical follow-up data of a prospective, consecutive cohort of patients who underwent TAA by a single surgeon from 1999 to 2013 with the Scandinavian Total Ankle Replacement (STAR) prosthesis. Methods: Patients undergoing TAA at a single US institution were enrolled into a prospective study. These patients were followed at regular intervals with history, physical examination, and radiographs; American Orthopaedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale scores were obtained and recorded. Primary outcomes included implant survivability and functional outcomes scores. Secondary outcomes included perioperative complications such as periprosthetic or polyethylene fracture. Between 1999 and 2013, a total of 138 STAR TAAs were performed in 131 patients; 81 patients were female. The mean age at surgery was 61.5 ± 12.3 years (range, 30-88 years). The mean duration of follow-up for living patients who retained both initial components at final follow-up was 8.8±4.3 years (range 2-16.9 years). Results: The mean change in AOFAS Ankle-Hindfoot scores from preoperative to final follow-up was 36.0 ± 16.8 ( P < .0001). There were 21 (15.2%) implant failures that occurred at a mean 4.9 ± 4.5 years postoperation. Ten polyethylene components in 9 TAAs (6.5%) required replacement for fracture at an average 8.9 ± 3.3 years postoperatively. Fourteen patients died with their initial implants in place. Conclusion: This cohort of patients with true intermediate follow-up after TAA with the STAR prosthesis had acceptable implant survival, maintenance of improved patient-reported outcome scores, and low major complication rates. Level of Evidence: Level IV, case series.

Abstract BACKGROUND: The Pipeline Embolization Device (PED) has emerged as a promising treatment for intracranial aneurysms. OBJECTIVE: To assess the safety and efficacy of the PED, to analyze the effect of operator experience on the complication rate, and to identify predictors of complications and obliteration. METHODS: A total of 109 patients with 120 aneurysms were treated with PED at our institution. The patient population was divided into 3 consecutive equal groups to assess whether overall and major complication rates decreased over time: group 1, patients 1 through 37; group 2, patients 38 through 73; and group 3, patients 74 through 109. RESULTS: The number of PEDs used was 1.40 per aneurysm. Symptomatic and major procedure-related complications occurred in 11% and 3.7% of patients, respectively. The rate of complications decreased from 16.2% in group 1 to 5.6% in group 3, and the rate of major complications fell dramatically from 10.8% in group 1 to 0% in groups 2 and 3 (P &lt; .05). Procedure time significantly decreased over time (P = .04). In multivariate analysis, previously treated aneurysms were predictive of procedural complications (P = .02). At the latest follow-up, 65.8% of aneurysms were completely occluded, 9.6% were nearly completely occluded, and 24.6% were incompletely occluded. In multivariate analysis, fusiform aneurysms (P = .05) and shorter angiographic follow-up (P = .03) were negative predictors of aneurysm obliteration. CONCLUSION: PED therapy may have an acceptable safety-efficacy profile. The risk of complications appears to decrease dramatically with physician experience, supporting the existence of a learning curve. Patients with previously treated aneurysms have higher complication rates, whereas fusiform aneurysms achieve lower obliteration rates.

Abstract Background Previous research on parastomal hernia repair following ileal conduit urinary diversion is limited. This nationwide cohort study aims to present the results of keyhole and Sugarbaker techniques in parastomal hernia repair in the setting of ileal conduit urinary diversion. Method All patients in this cohort underwent primary elective parastomal hernia repair following ileal conduit urinary diversion in four university hospitals and one central hospital in Finland in 2007–2017. Retrospective clinical data were collected from patient registries to compare keyhole and Sugarbaker parastomal hernia repair techniques. The primary outcome was parastomal hernia recurrence during the follow-up from primary surgery to the last confirmed follow-up date of the patient. The secondary outcomes were reoperations during the follow-up and complication rate at 30 days’ follow-up. Results The results of 28 hernioplasties were evaluated. The overall parastomal hernia recurrence rate was 18%, the re-operation rate was 14%, and the complication rate was 14% during the median follow-up time of 30 (21–64) months. Recurrence rates were 22% (4/18) after keyhole repair and 10% (1/10) after Sugarbaker repair. Re-operation rates referred to keyhole repair were 22% and Sugarbaker repair 0% during follow-up. The majority of reoperations were indicated by recurrence. Complication rates were 17% after keyhole and 10% after Sugarbaker repair during the 30 days’ follow-up. Conclusion The results of parastomal hernia repair in the setting of ileal conduits are below optimal in this nationwide cohort comparing keyhole to Sugarbaker repair in elective parastomal hernia repair. Nonetheless, the Sugarbaker technique should be further studied to confirm the encouraging results of this cohort in terms of recurrence.

Purpose: The purpose of our study was to examine outcomes and compare length of stay after extravesical and intravesical ureteral reimplantation at our institution. Materials and Methods: Retrospective review was performed of 30 patients (55 ureters) with vesicoureteral reflux who underwent either the Cohen (intravesical) cross-trigonal procedure or the extravesical (detrusorrhaphy) approach. Each patient had documented follow-up consisting of a postoperative renal ultrasound and/or a voiding cystourethrogram (VCUG). Inclusion criteria was the presence of primary vesicoureteral reflux. Exclusion criteria were patients who had undergone a previous repair and patients in whom results of neither the renal ultrasound nor the VCUG were available. Results: There were no significant cases of obstruction or wound infection with either approach. Two patients who underwent the extravesical approach had persistent reflux on VCUG three months postoperatively, but both resolved by fifteen months. Average length of stay was only 3.00 ± 1.33 days for the extravesical approach, compared to 5.36 ± 1.75 days for the intravesical approach ( P = .0003 ). Conclusions: Given that by fifteen months success rates were the same with either approach, the extravesical approach is comparable to the intravesical technique and is a viable option in terms of outcome and economics given the shorter length of hospital stay.

Abstract The incidence of vesicourethral anastomotic stenosis (VUAS) post radical prostatectomy varies from 1 to 26%. Current treatment can be challenging and includes a variety of different procedures. These range from endoscopic dilations to bladder neck reconstruction to urinary diversion. We investigated a 2-stage endoscopic treatment, using the thermo-expandable Memokath®045 bladder neck stent to manage patients with VUAS post radical prostatectomy. We retrospectively reviewed 30 patients, between 2013 and 2017, who underwent a Memokath®045 stent insertion following failed primary treatment (dilation and clean intermittent catheterisation) for VUAS. The mean interval time between prostatectomy and Memokath®045 stent insertion was 13 months. The mean follow-up time was 3.6 years with all patients having a minimum of 12-month follow-up. All patients had two previous attempts at endoscopic dilatation with or without incision and a trial of clean intermittent catheterisation. During stage 1, the anastomotic stricture is dilated/incised to diameter of 30 Fr, the stricture length is measured, and a catheter is left in situ. One to 2 weeks later, post haemostasis and healing, an appropriately sized Memokath®045 stent is inserted. The stent is then removed 1-year post-op. Our series of patients had a median age of 62 (54–72). Most patients (26) had a robot-assisted radical prostatectomy (RARP) or salvage procedure. Results showed improvement in IPSS scores, IPSS quality of life scores, Qmax and PVR after the Memokath®045 stent was removed compared to pre-operation. With a minimum of 12 months post stent removal, 93% of patients were fully continent, whilst 7% of patients were socially continent. 2 (7%) patients had their stents removed and not replaced due to re-stricturing and stone formation. However, no urinary tract infections, stricture recurrence or urinary retention was observed in the rest of the cohort (93%). Overall, the Memokath®045 stent was successful in treating 93% of our patients with VUAS. Our series had minimal complications that were managed with conservative measures and in three patients’ re-operation was needed. In conclusion, the Memokath®045 stent is a minimally invasive technique with faster recovery time compared to other techniques such as bladder neck reconstruction or urinary diversion. Additionally, it provides superior patency results compared to other techniques such as bladder neck incision and injection of Mitomycin C. Therefore, this management option should be considered in the management of VUAS.
