Background: Middle calyx access has been underused in percutaneousnephrolithotomy (PCNL), especially in the supine position.We compared the safety and efficacy outcomes between middlecalyx and lower calyx accesses in the complete supine PCNL in anon-randomized single-surgeon clinical study.Methods: Between February 2008 and October 2011, 170 patientsunderwent posterior subcostal single tract complete supine PCNLwith one-shot dilation and middle calyx (n = 48) and lower calyx(n = 122) accesses. Stone location and surgeon decision determinedtarget calyx for access. Inclusion criteria were pelvis stones,staghorn stones and multiple location stones. Exclusion criteriawere renal anomalies, only upper calyx stones, only middle calyxstones and only lower calyx stones. Important parameters werecompared between the two groups. A p value of <0.05 was consideredsignificant.Results: Two groups were similar in important patient- and stonerelatedparameters. Mean operative time (60.7 minutes), meanpostoperative hospital stay (1.84 days) and mean hemoglobin drop(0.67 g/dL) in the middle calyx group were significantly lesser thanin the lower calyx group (80.1 minutes, 2.19 days, 1.36 g/dL). Themiddle calyx group (89.6%; 79.6%) had a higher stone-free rate(p = 0.054) and efficiency quotient than the lower calyx group(76.2%; 61.6%). In the middle calyx group (10.4%; 2.1%), complicationand transfusion rates were lesser (p > 0.05) than lowercalyx group (14.8%; 7.4%). No significant difference (p = 0.40)was seen between two groups using the modified Clavien classificationof complications.Interpretation: Middle calyx can be an optimal access in PCNLwith the complete supine position for many of upper urinary tractstones due to its superior outcomes.

Introduction: Renal calculus disease is an age old disease of human being. PCNL (Percutaneous nephrolithotomy) stands as a gold standard treatment for large renal calculus which is traditionally being done in prone position. Objective: To evaluate the safety and efficacy of supine PCNL versus prone PCNL comparing intraoperative time, requirement of relook PCNL, post op hemoglobin drop, post operative hospital stay, post operative complication, SFR ( stone free rate). Methods and materials: It is a prospective study done in Urology department in a tertiary care center in Eastern India between October 2017 and October 2018. A total of 84 patients with lower calyceal renal stones underwent PCNL, 42 of them in supine and 42 in prone position. Lower calyceal stone, size measuring 1 to 2 cm were included in the study. Results: The mean intra operative time was 91.76 min in supine group and 85.43 min in prone group with a p value of 0.115. The mean hemoglobin drop was 1.11 g/dl and 1.18 g/dl in supine and prone position, respectively ( p value 0.75). The mean post operative hospital stay was 4.1 and 3.86 days in supine and prone group ( p value 0.58), respectively. Two patients in each group require relook PCNL. Stone free rate at 1 month was 95.23% and 90.47% ( p value 0.9), respectively in case of supine and prone group. Conclusion: Supine PCNL is feasible, comparable to prone PCNL in respect to operative parameters with relatively higher stone free rate though statistically insignificant.

Objective: To compare the stone free rates on patients with staghorn, renal pelvic, and inferior calyx stones with stone burden < 20 mm, 21-30 mm, and > 30 mm following percutaneous nephrolithotomy (PCNL) in Cipto Mangunkusumo General Hospital Jakarta. Material & methods: The data were collected retrospectively from PCNL medical records in Cipto Mangunkusumo General Hospital Jakarta between January 2000 and March 2011. Six hundred and twenty-three patients with 651 kidney stones underwent PCNL. The inclusion criteria were staghorn stones, renal pelvic stone, and inferior calyx stone. All cases outside these three criteria and incomplete data were excluded. Stone free status was defined as no residual fragment on radiography or ultrasonography. Results: As many as 364 kidney stones from 344 patients were included, with 47.8% cases of staghorn stones, 31.9% cases of renal pelvic stones, and 20.3% cases of inferior calyx stones. Overall, 273 (75%) cases were defined as stone free. In group < 20 mm, 4 staghorn stones (100%), 18 renal pelvic stones (81.8%), and 34 inferior calyx stones (94.4%) were cleared (p = 0.811). In group 21-30 mm, 20 staghorn stones (95.2%), 52 renal pelvic stones (91.2%), and 26 inferior calyx stones (92.9%) were cleared (p = 1.000). In group > 30 mm, 83 staghorn stones (55.7%), 28 renal pelvic stones (75.7%), and 8 inferior calyx stones (80%) were cleared (p = 0.037). Conclusion: PCNL is an important tool for treating various kinds and sizes of kidney stones with high stone free rate.

Staghorn Stones

Background: Staghorn stones are mostly treated by percutaneous nephrolithotomy (PCNL), either with an upper-pole (UP) or non-upper (lower- or middle-) pole (NP) approach. NP access has a lower risk of bleeding and thoracic complications but may not be sufficient for complete stone clearance. UP access is advocated as the preferred approach, because of direct access to the collecting system. However, it is associated with a higher complications rate, including pneumothorax and hydrothorax, and a higher risk of bleeding. This meta-analysis aimed to describe the outcomes and safety of PCNL for staghorn stones using UP and NP approaches. Methods: A systematic literature review was conducted using several databases such as: PubMed; EBSCO; Science Direct; Cochrane and Google Scholar. Data from all selected articles were extracted by two independent reviewers. Relevant parameters explored using Review Manager V5.3. Results: Five comparative studies of staghorn stones involving 384 renal units were analyzed; 176 cases used the UP approach and 208 the NP approach. There was no significant difference in stone-free rate between these approaches, with 74.4% undergoing the UP approach and 71.1% the NP approach considered stone-free (OR: 1.55; 95% CI: 0.92-2.63; P=0.10). The rate of thoracic complications (hydrothorax and pneumothorax) did not differ significantly (OR: 3.14; 95% CI: 0.63-15.62; P=0.16). However, we noted that 5 of 176 patients that underwent the UP approach experienced thoracic complications. The incidence of post-procedural fever and sepsis is similar (OR: 1.18; 95% CI: 0.52-2.64; P=0.69). Neither post-procedural urine leakage (OR: 2.03; 95% CI: 0.70-5.85; P=0.19) nor requirement of blood transfusions (OR: 0.49; 95% CI: 0.14-1.76; P=0.27) differed significantly. Conclusion: PCNL with UP access for staghorn stone has a similar stone-free rate to the NP approach. Thoracic complication rate which was believed to be higher in the UP group is also deemed similar with NP access.

<b><i>Objectives:</i></b> The aim of this study was to provide a randomized controlled trial comparing the outcomes of different access sizes used in the solo ultrasonic-guided minimally invasive percutaneous nephrolithotomy (mini-PCNL). <b><i>Methods:</i></b> From January 2018 to December 2019, a total of 160 cases with single renal stones of &#x3c;25 mm were randomized to undergo mini-PCNLs with Fr16, Fr18, Fr20, or Fr22 accesses. All accesses were established with the axis of the target calyx as the marker for puncture location and then expanded to the desired size. Hemoglobin reduction, operative time, stone-free rate, complications, etc., were all recorded and assessed. <b><i>Results:</i></b> The demographic data were similar, and there were no significantly intergroup differences in stone-free rate, complications, and hospital stay time. The hemoglobin reduction was comparable and was 0.9 ± 0.6, 0.9 ± 0.7, 1.0 ± 0.5, and 1.1 ± 0.7 g/dL for the groups Fr16, Fr18, Fr20, and Fr22, respectively. The operative time was 53.4 ± 14.5, 48.5 ± 15.2, 42.8 ± 13.3, and 43.3 ± 13.1 min for the 4 groups, which decreased significantly from group Fr16 to Fr20, but there was no significant difference between Fr20 and Fr22 groups. <b><i>Conclusions:</i></b> The axis of target calyx is a reliable marker for establishment of percutaneous renal access under ultrasonic guidance. The surgical outcomes of different access sizes were comparable, but the operation time was significantly shortened with the increase of size. However, Fr22 was not more efficient than Fr20.

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.

Background: Nephrolithiasis is highly prevalent across all demographic groups in the india and beyond, and its incidence rates are rising. In addition to the morbidity of the acute event, stone disease often becomes a lifelong problem that requires preventative therapy to diminish ongoing morbidity. Objective of this study to evaluate the safety and efficacy of minimally invasive percutaneous nephrolithotomy (PCNL) in the management of large and complex renal stone.Methods: This retrospective study includes 75 renal calculi patients with 100 renal units with large and complicated stone >20 mm. Stones were classified into simple (isolated renal pelvis or isolated calyceal stones) or complex (partial or complete stag horn stones, renal pelvis stones with accompanying calyceal stones). Then various parameter like decrease haemoglobin, surgical complication, creatinine level, duration of surgery etc were compared between simple and complex stones patients by calculation p value using online student t test calculator. P value less than 0.01 considered as a difference of significance.Results: The mean stone size was 35.5±20.37 mm and mean operative duration was 60±35.3 min. In all, cases 60 (80%) were stone-free after the first procedure and another 10 needed an auxiliary procedure (5 second-look PCNL, 3 extracorporeal shockwave lithotripsy-ESWL, 2 ureterorenoscopy, and) to become stone-free, resulting in a 93.33% stone-free rate. Complications occurred in 9 procedures (12%).Conclusions: From this study, it would be concluded that Minimally invasive PCNL provided significantly higher stone-free rate and efficiency quotient for management of urinary calculi. Overall complications are usually observed in patients having intraoperative hypotension and increased intra operative time.

Objective: This study aims to compare the safety, efficacy, and other surgical outcomes of supine PCNLs performed with and without the use of supporting pad. Material & Methods: We enrolled 27 patients who undergone PCNL procedure with supine position for renal stones with all sizes between January - December 2019. Divided into two groups, operated with and without supporting pad, with 13 and 14 patients respectively. Inclusion criteria are patients with renal stones, including staghorn, multiple calyx, and proximal ureteral stones. Meanwhile, pediatric patients under 12 years old, uncorrectable bleeding disorders, active urinary infection, and pregnancy are excluded. Results: Our observation showed no statistically significant difference between the two groups, although blood loss and length of stay in supporting pad showed better results. A statistically significant difference was found in stone-free-rate (P = 0.006) favoring in supine PCNL with supporting pad. Conclusion: Supine PCNL with support padding may be a safe and more effective choice to treat renal stones. Nevertheless, the patient’s anatomic variations may influence this. Thus, a prospective study with a larger population is needed to verify our outcomes.

Introduction: Percutaneous Nephrolithotomy (PCNL) is a procedure of choice for large renal calculi. It is a common urological procedure. PCNL can be performed in various positions. Aim: To determine the surgical outcomes in patients undergoing PCNL in supine and prone positions. Materials and Methods: A cohort study was conducted on patients with renal and upper ureteral stones who underwent PCNL in either prone or supine position between August 2019 to August 2020 at Urology Department, JSS Hospital, Mysuru. Supine PCNL was done in the flank Free Oblique Supine Modified Lithotomy (FOSML) position. All the procedures were performed under fluoroscopy guidance. Surgical outcomes including operative time, length of hospital stay, Stone Free Rate (SFR), radiation dose, and postoperative complications were evaluated. The collected data was tabulated and frequency (n) and percentage (%) analysis was performed. The Chi-square test was used to find the level of significance. Results: A total of 70 patients were included in the study and out of which 35 patients were in the supine (46.37±14.73 years, 28 males and 7 females) and 35 patients (47.54±12.45 years, 23 males and 12 females) were in the prone PCNL groups. Statistically significant difference was observed in the mean operating time in the supine and prone PCNL groups (81.43 vs 127.71 minutes; p-value=0.001), with a higher stone-free rate (94.29% vs 91.43%; p-value=0.643) observed in the supine PCNL group. One patient in supine group had postoperative sepsis and one patient in prone group had bleeding requiring transfusion. The Visual Analog Scale (VAS) score in supine PCNL was (5.08±0.32) less than in prone group (8.03±0.40) (p-value <0.001). Conclusion: PCNL in the supine position compared with the prone position demonstrates significantly lower operative time with similar SFR and lower VAS score.

Objective. To evaluate and compare the efficacy and safety of retrograde versus antegrade ureteroscopic lithotripsy for the treatment of large proximal ureteral stones.Patients and Methods. We retrospectively analyzed the medical records of patients with proximal ureteral stones >15 mm, treated in our institution from January 2011 to January 2016. Intraoperative parameters, postoperative outcomes, and complications were recorded and compared between the two techniques.Results. Our analysis included 57 patients. Thirty-four patients (59.6%) underwent retrograde and 23 patients (40.4%) underwent antegrade ureteroscopy. There was no significant difference in patients’ demographics and stone characteristics between the groups. Stone-free rate was significantly higher (p=0.033) in the antegrade group (100%) compared to retrograde one (82.4%). Fluoroscopy time, procedure duration, and length of hospitalization were significantly (p<0.001) lower in retrograde approach. On the other hand, the need for postoperative stenting was significantly lower in the antegrade group (p<0.001). No difference was found between the groups (p=0.745) regarding postoperative complications.Conclusions. Antegrade ureteroscopy is an efficient and safe option for the management of large proximal ureteral stones. It may achieve high stone-free rates compared to retrograde ureteroscopy with the drawback of longer operative time, fluoroscopy time, and length of hospitalization.

<b><i>Background:</i></b> Pre-stenting (PS) on the outcomes of semirigid and flexible ureteroscopic lithotripsy for a different upper urinary urolithiasis remains controversial. We performed a meta-analysis comparing the outcomes of ureteroscopic lithotripsy between PS and non-PS. <b><i>Materials and Methods:</i></b> Randomized, controlled trials and observational studies comparing PS and non-PS were identified from electronic databases. Stone-free rate (SFR), operative time, and complications were compared by qualitative and quantitative syntheses (meta-analyses). <b><i>Results:</i></b> Eleven articles were included in this study. Nearly, all of recently published studies exhibited relatively moderate or high quality during quality assessment. PS was more likely to achieve good SFR compared with non-PS (<i>p</i> &#x3c; 0.00001). The subgroup results indicated that PS improved the SFR for renal stones and the stones dealt by flexible ureteroscopy (<i>p</i> = 0.0002; <i>p</i> &#x3c; 0.0001, respectively; some ureteral stones were dealt by flexible ureteroscopy). Ureteral stones and the stones dealt by semirigid ureteroscopy were not influenced by PS (<i>p</i> = 0.62; <i>p</i> = 0.90, respectively). PS is equal as non-PS in terms of operative time for renal stones and the renal and ureteral stones dealt by flexible ureteroscopy (<i>p</i> = 0.47; <i>p</i> = 0.05). No significant difference was found in major complications between the 2 groups for total or for the subgroup of renal stones (<i>p</i> = 0.3; <i>p</i> = 0.69). <b><i>Conclusions:</i></b> For ureteral stones or the stones dealt by semirigid ureteroscopy, PS does not show any benefits. For renal stones or the stones dealt by flexible ureteroscopy, PS improves the SFR and may be as safe as non-PS.
