Introduction: We compare percutaneous nephrolithotomy (PCNL) and open surgery in the treatment of staghorn stones in children.Methods: We retrospectively reviewed the electronic records of children who underwent treatment for staghorn stones between September 2000 and August 2013. They were divided between Group 1 (patients who underwent PCNL) and Group 2 (patients who underwent open surgery). We compared stone-free and complications rates, need for multiple procedures, and hospital stay.Results: The study included 41 patients (35 boys and 6 girls), with mean age 7.4 ± 3.1 years (range: 2–15). Of these 41 patients, 26 had unilateral renal stone and 15 had bilateral renal stones. The total number of treated renal units was 56: 28 underwent PCNL and 28 underwent open surgery. The complication rate was comparable for both groups (32% for open surgery vs. 28.6%, p = 0.771). Multiple procedures were more needed in PCNL group (60.7% vs. 32% in open surgery, p = 0.032). The stone-free rate was 71.4% after PCNL and 78.6% after open surgery (p = 0.537). A significant difference was observed in shorter hospital stay after PCNL (5 vs. 8.8 days, p < 0.001). Our study’s limitations include its retrospective design and relatively small sample size.Conclusions: For the treatment of staghorn stones in children, PCNL was comparable to open surgery in complication and stone-free rates. PCNL had the advantage of a shorter hospital stay and open surgery showed a decreased need for multiple procedures.

This study purpose to analyze the differences in the effectiveness of PCNL and open surgery in patients with staghorn stones. We searched the literatures from PubMed and ScienceDirect from year 2005 until 2020. The method used in this study was a systematic review with a quantitative statistical approach (meta-analysis) using primary research data. From 4 studies there were 148 cases of PCNL and 98 cases of open surgery. PCNL had lower postoperative stone-free rate than open surgery (OR 0.168). PCNL had a lower final stone-free rate than open surgery (OR 0.603). The number of patients who had complications with PCNL was lower than open surgery (OR 0.451). The number of patients receiving blood transfusions on PCNL was lower than for open surgery (OR 0.494). Patients who received PCNL procedure required a shorter hospital stay than open surgery (MD -3,234). The number of patients who received additional therapy modalities on PCNL was lower than open surgery (OR 1.917). The conclusions obtained in this study indicate that there are differences in the effectiveness of PCNL and open surgery for patients with staghorn stones.

Abstract. The present study aimed to assess the effectiveness and safety of mini-percutaneous nephrolithotomy (mPNL) in comparison with standard percutaneous nephrolithotomy (sPNL) for the treatment of complex nephrolithiasis. Methods. During the period from 2012 to 2020, 1021 patients with solitary (10.0-30.0 mm), staghorn and multiple renal calculi were retrospectively divided into two groups: sPNL (500 patients) and mPNL (521 patients). The groups were compared by the stone-free rate (%, SFR), the duration of the surgery, complications and hospital stay. Results. SPNL and mPNL were highly effective procedures for the treatment of nephrolithiasis. The mPNL group had longer operative times (81.0±15.5 vs 69.1±13.9 min, p<0.001) and higher frequency tubeless/totally tubeless procedures (41.1 vs 6.8%, p<0.001). mPNL showed a higher SFR (96.4 vs 91.8%, р=0.002 in patients with complete staghorn (90.1 vs 77.3%, p<0.05) and multiple kidney stones (89.5 vs 70.8%, p=0.03). Postoperative decrease in hemoglobin was lower in mPNL group 1.1±0.34 vs 2.1±0.26 g/dl (p<0.001). The incidence rate of urinary tract infections and postoperative hospital stay was lower in the mPNL group: 7.3 vs 13.2%, p=0.03 and 1.9±0.6 vs 4.3±2.4 days, р<0.001. Conclusions. MPNL is a safe and effective treatment for patients with complex renal stones with an improved stone-free rate and lower complication rate and shorter hospital stay. Smaller diameter tract in mPNL procedures was associated with a longer duration of surgery.

Objectives: To see the effect of intra operative antegrade flexible nephroscopy during Percutaneous nephrolithotomy on stone free rate. Methods: We retrospectively reviewed electronic medical records of patients who underwent percutaneous nephrolithotomy from 2010 to 2017 for renal stones >2cm. Patients found eligible were divided in, Group-I who did not have intraoperative Flexible nephroscopy and Group-II who had flexible nephroscopy during percutaneous nephrolithotomy. All procedures were done by senior consultants. Variables like Mean age, side, stone size, skin to stone distance and Hounsfield unit were compared. Outcomes like Stone free rate, hospital stay and operative time were compared between the groups. Results: The study included 248 patients, consisting 85 (34.3%) females and 163 (65.7%) males. Mean age ± SD was 45.8±13.8 years. Both group were similar in characteristics like mean age, stone size, skin to stone distance and Hounsfield units. The overall stone free rate was 71%. It was not significantly different between the groups, 76% in Group-II vs. 67% in Group-I. However stone free rate markedly improved with flexible nephroscopy in patients with staghorn calculi. Mean operative time and hospital stay were similar between the groups. Conclusions: Intraoperative flexible nephroscopy during percutaneous nephrolithotomy significantly increases stone free rate in patients with staghorn stones. doi: https://doi.org/10.12669/pjms.37.3.3565 How to cite this:Masood Y, Iqbal N, Farooq RM, Iqbal S, Khan F.

Background: Percutaneous nephrolithotomy (PCNL) was applied in the prone position until recently. But also, in recent years supine positions was applied in patients with kidney stones. Predicting how much renal stones can be cleared after surgery and possibility of complications is an important question for both surgeons and patients. Therefore different scoring systems are used to evaluate outcomes of PCNL before surgery. Patients and methods: Between 2018 and 2020, 80 patients with renal stone who underwent PCNL in the supine position were evaluated preoperatively by S.T.O.N.E. and Guy’s scoring systems (GSS). The predictions of both scoring systems for stone-free and complication rates in patients who underwent PCNL in the supine position were evaluated. Also, these scoring systems were compared among themselves for reliability. Result: In both scoring systems, there was a statistically significant difference between postoperative stone-free (SF) and residual stone (RS) of patients and in predicting the likelihood of complications in patients. No statistically significant difference was found between the two scoring systems in predicting the stone-free rate. Conclusion: Our findings revealed that S.T.O.N.E. nephrolithometry and Guy’s score systems can be used effectively to predict stone-free rate, complications, and operation duration in supine position PCNL for renal stones.

Abstract Corresponding Background Stone size is a key factor in the determination of the success of author: treatment modalities. Recently, there has been a great advancement in technology for minimally invasive management of urinary stones such as percutaneous nephrolithotomy, ureteroscopy, shockwave lithotripsy, and retrograde internal Surgery Aim of the Work to compare the outcome of PCNL and RIRS in medium sized renal pelvic stoned in adults regarding operative time, fluoroscopic time, intra and postoperative complications, stone free rate, hospital stay and postoperative stenting. Patients and Methods This prospective randomized clinical study was conducted on 30 patients from April 2019 to January 2020, all patients had single renal pelvic stone (10 to 20 mm) and had no contraindication to perform these operations at the Urology department, Ain Shams University Hospitals and National Institute of Urology and Nephrology. The patients were randomized by (1 : 1) manner for either PCNL or RIRS. All preoperative, intraoperative and postoperative parameters, results and complications between both groups were recorded. Results Mean fluoroscopic time and hospital stay were significantly greater in PCNL group than RIRS group. The stone free rate was 86.7% (13/15) in PCNL group and 80% (12/15) in RIRS group and for complications (according to Cliven-Dindo score) there were no statistically significant difference between two groups.Complications occurred in 3(20%) patients in PCNL group and in 2(13.3%) patients in RIRS group. PCNL and RIRS are safe and effective methods for medium sized renal pelvic stones. For selected patients, RIRS may represent an alternative therapy to PCNL, with acceptable efficacy and low morbidity. RIRS compared to PCNL offers the best outcome in terms of radiation exposure and hospital stay. Conclusion RIRS may represent an alternative therapy to PCNL, RIRS compared to PCNL offers the best outcome regarding radiation exposure and hospital stay.

Background: The aim of the study is to investigate whether laparoscopic pyelolithotomy (LPL) could be used to manage large renal pelvic stones, generally considered excellent indications for percutaneous nephrolithotomy (PNL).Methods: This study was performed from May 2009 to March 2012 at Al-Azhar University Hospitals (Assiut and Cairo), Egypt. It included two groups of patients with large renal pelvic stones; only patients with stones 2.5 cm2 or greater were included. Group1 included 40 patients treated by PNL and Group 2 included 10 patients treated by LPL. The differences between the two procedures were compared and analyzed.Results: There was no difference between the two groups regarding patient demographics and stone size. There was a statistically significant difference between the groups regarding mean estimated blood loss (65 ± 12.25 [range: 52.75- 77.25] vs. 180 ± 20.74 [range: 159.26- 200.74] mL, p ≤ 0001), mean hospital stay (2.3 ±0.64 [range: 1.66- 2.94] vs. 3.7 ± 1.4 [range: 2.3- 5.1] days, p ≤ 0.006), rate of postoperative blood transfusion (0% vs. 4.8%,p ≤ 0.0024), and stone-free rate (80% vs. 78.6%, p ≤ 0.23). The mean operative time was significantly longer in Group 2 (LPL) (131 ± 22.11 [range: 108.89-153.11) vs. 51.19 ± 24.39 [range: 26.8-75.58] min, p ≤ 0001), respectively.Conclusion: Although PNL is the standard treatment in most cases of renal pelvic stones, LPL is another feasible surgical technique for patients with large renal pelvic stones.

Objectives: This study aimed to assess which of extracorporeal shock-wave lithotripsy (SWL), ureterorenoscopy (URS) or percutaneous nephrolithotomy (PCNL) offers the best stone-free rate (SFR) for 1–2 cm renal stones. Patients and methods: A total of 31 patients with renal stones between 1 and 2 cm were randomised to SWL, URS or PCNL. Repeat treatments or alternatives were performed until the patient was stone free or clinically in no further need of treatment. All patients were assessed with computed tomography scanning independently reviewed by a radiologist blinded to the treatment. Results: Overall, 10 well-matched patients were randomised to SWL, 11 to URS and 10 to PCNL. SFRs were 60% for SWL, 55% for URS and 80% for PCNL (no significant difference). The mean number of procedures required were 2.6 (range 1–7) for SWL, 2.5 (range 1–4) for URS and 1.3 (range 1–3) for PCNL ( p=0.072). There were no major complications, but 50% of SWL had minor complications compared with 9% for URS and 20% for PCNL. Conclusion: The results for SWL were disappointing for SFR, number of procedures and complications. In common with other recent studies, the SFR following URS was also poor. PCNL had the best results for SFR with the fewest procedures. We calculate that an adequately powered study will require 42 patients per arm. Level of evidence Level 2b

Background We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm. Methods We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals. Results We included 25 studies (1831 patients). LPL was associated with a significantly higher stone-free rate, lower rates of blood loss, complementary treatment, blood transfusion, and complications, and less reduction in hemoglobin level compared with PCNL. LPL and PCNL were similar in terms of duration of hospital stay, conversion rate, changes in glomerular filtration rate and creatinine level, and mean time of postoperative analgesia. However, LPL was associated with a longer operation time than PCNL. Conclusion LPL appears to be more effective and safer than PCNL in patients with large renal stones, by increasing the stone-free rate and reducing blood loss, complementary treatment, blood transfusion, and complications compared with PCNL. LPL may thus be a useful modality for treating patients with large renal stones.

Introduction: In this study, we aimed to evaluate the safety and efficacy of the percutaneous nephrolithotomy procedure performed with adult-sized instruments in pediatric cases with staghorn kidney stone. Methods: We retrospectively evaluated the efficacy and safety of 94 percutaneous nephrolithotomy procedures performed during 15 years in a single center for 82 pediatric patients with staghorn calculi using adult-sized instruments (24-Fr nephroscope). Stone free status was defined as complete clearance of the stones or the presence of insignificant residual stones of <3 mm in diameter. Results: The mean age was 108 ± 53 months (range, 14–180 months). There were 39 patients (48%) with complete staghorn stones and 43 cases (52%) with partial staghorn. We fulfilled 91.4% of operations through a single access. The stone free rate was 86.6% after one percutaneous nephrolithotomy session. In total, seven patients referred for shock wave lithotripsy and four cases were scheduled for the second percutaneous nephrolithotomy session. Fever occurred in 18 patients (21%) and bleeding requiring transfusion in four children (5%). Prolonged leakage from nephrostomy site requiring anesthesia for double J stent placement occurred in one patient. No grade IV or V Clavien complication occurred. Conclusion: The success rate and complications of percutaneous nephrolithotomy with adult-size instruments in pediatric patients are acceptable.
