Objective: This study aims to compare outcomes of supine percutaneous nephrolithotomy to prone percutaneous nephrolithotomy as a traditional approach in Hasan Sadikin Hospital Bandung. Material & Methods: Data was taken from urology’s database between 2003-2012, which contain data of prone position (2003-2007), and supine position (2008-2012). Three hundred forty-nine patients were included in this study. We reviewed data on demography, stone burden, operating time, stone-free rate, transfusion rate, hospital stay, and major complications. Results: Of 174 patients underwent prone position, and 175 patients were part of the supine position. Age means of prone position was 51.0 years old, the supine position was 50.5 years old. The number of male patients was 65.5% for prone, and 66.1% for supine. The mean stone's largest diameter of prone was 23.87 mm, supine was 22.36 mm. The operating time of prone was 107 minutes; supine was 90 minutes. The stone-free rate of prone was 94.7%; supine was 91.3%. The mean hospital stays of prone was 14.3 days; supine was 9.6 days. The transfusion rate of prone position was 8.9%, supine was 7.2%. No major complications were recorded. Conclusion: Higher stone-free rates are achieved with patients in the prone position during PCNL. Supine position has shorter operating time, and hospital stay, lower blood transfusion rates. The complication rate is not different between the two positions.

Background: The aim of the study is the compare efficacy and safety of percutaneous nephrolithotomy in supine and prone positions. Percutaneous nephrolithotomy is conventionally performed in prone position but in recent years numbers of supine percutaneous nephrolithotomies is increasing globally.Methods: The hospital based cross-sectional observational study was conducted in the Department of Urology, Bir Hospital from July 2018 to January 2020. A total of 81 consecutive patients undergoing percutaneous nephrolithotomy were divided into two groups, with 38 patients in Supine (Group 1) and 43 patients in Prone (Group 2) positions, respectively. Patient’s demographics, access time, operative duration, stone free rate, radiation dose and duration, irrigation fluid volume, post-operative hemoglobin drop and complications were compared.Results: Demographic and stone characteristics were comparable in both groups. Supine Group (Group 1) had significantly shorter operative duration than Prone Group (Group 2), 44.63 ± 12.44minsvs 53.02 ±12.67mins (p< 0.04). The mean radiation duration was 99.11 ± 61.17secs in Group 1 and 108.40 ± 51.65 secs in Group 2 (p=0.46), respectively. Although the mean radiation dose was lower in Group 1 (375.1µGym2) than in Group 2 (465.7 µGym2), it was not statistically significant(p=0.24). The stone free rate at 1 month duration were comparable with 92.1% and 93.02% in Group 1 and Group 2 respectively (p=0.16). Overall complication rates were similar in both groups (15.7% in Group 1 vs 16.2% in Group 2), respectively. None of the patients in both groups had complications higher than Clavien IIIa.Conclusions: PCNL in supine position has significantly shorter operative time with similar complications and stone free rates as compared to prone position.Keywords: percutaneous nephrolithotomy; prone position; supine position

Background: The decision for using supine or prone position in percutaneous nephrolithotomy (PCNL) is still debatable. The aim of this study is to compare the efficacy and safety profile of the supine and prone position when performing PCNL. Methods: A systematic electronic search was performed using the database from MEDLINE, Cochrane library and Google Scholar from January 2009 to November 2019. The outcomes assessed were stone free rate, major complication rate, length of hospital stay and mean operation time. Results: A total of 11 articles were included in qualitative and quantitative analysis. The efficacy of PCNL in supine position as determined by stone free rate is significantly lower than in prone position (OR: 0.74; 95% CI: 0.66 – 0.83; p<0.00001), However, major complication rate is also lower in the supine group compared with the prone group (OR: 0.70; 95% CI: 0.51 – 0.96; p=0.03). There is no statistically significant difference in the length of hospital stay and mean operation time between both groups. Conclusion: Prone position leads to a higher stone free rate, but also a higher rate of major complication. Thus, the decision of using which position during PCNL should be based on the surgeon’s experience and clinical aspects of the patients.

Background: Renal stone disease is a common problem in children in developing countries. Its prevalence in children varies from 5% to 15%. It is suggested that anatomic abnormalities, recurrent urinary tract infections, metabolic disturbances, dietary and environmental factors are the predisposing factors.The aim of this study is to evaluate the safety and efficacy of percutaneous nephrolithotomy in children.Methods: Between May 2012 and Dec 2016, 25 children with renal stone diseases underwent percutaneous nephrolithotomy and were evaluated for stone free rate, complications, blood transfusion rate, sandwich therapy, etc.Results: The mean age of children was 9.3 years (7-15 years) and the mean size of the stone was 20 mm (13-27 mm). The anatomical location of stone was important in terms of stone clearance. Three patients needed blood transfusion. The overall stone free rate was 88% before discharge. Three patients had residual stones and were treated with extracorporeal shockwave lithotripsy. Complications included fever, haematuria, ileus and urine leak. No major complications were noted. There were no significant differences in haemoglobin and creatinine levels before and 12 hours after the surgery.Conclusions: Percutaneous nephrolithotomy (PCNL) can be considered a safe, effective and feasible modality of treatment for children with an average of 2 cm sized renal stones.

Introduction: The horseshoe kidney is extremely rare, the incidence being one in every 400 - 800 patients. In a recent review of more than 15000 radiographic imaging studies, the incidence was one in every 666 patients. The renal stone formation in horseshoe kidney is around 20-80%. Percutaneous nephrolithotomy is the most accepted modality of treatment . This study was carried out to find the outcome of percutaneous nephrolithotomy in horseshoe kidneys. Methods: Between May 2013 and November 2017, 11 adult patients(12 renal units) with stones in horseshoe kidneys underwent percutaneous nephrolithotomy in the department of urosurgery, Kathmandu Medical College and Teaching Hospital and were evaluated for the operating time, stone free rate , complications and hospital stay. Data analysis was done using Statistical Package for the Social sciences (SPSS) Version 20. Categorical data were analysed by using Fisher exact test. Results: The mean age of the patients was 30.9 years (SD = 10.3) and the mean stone burden was 385.83 mm2 (SD = 331.3). The overall stone free rate was 83.33%. The two patients with residual stones when counselled for Extracorporeal shock wave lithotripsy, refused for it and decided to be on follow up. No auxiliary procedure was done. The complications noted were of Clavien-Dindo grade I and II. No pleural or bowel injury was seen. One patient needed blood transfusion. Conclusions: Percutaneous nephrolithotomy is safe and effective in the management of stones in horseshoe kidneys. It does not carry increased risk than reported in normal kidneys.

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 the feasibility, safety and efficacy of one-shot dilation (OSD) in standard percutaneous nephrolithotomy (PCNL). Methods: This is a prospective, single -center study conducted between January 2017 to June 2019. Patients who underwent PCNL using one shot dilatation (21 – 24 Fr) for access in PCNL were included in the study. Access time, fluoroscopy time, successful dilation time, stone free rate, decrease hemoglobin level and transfusion rate, complication rate, length of post operative hospital stay, cost were recorded. Data was analyzed and reported using summary statistics. Results: A total of 30 patients were enrolled in this survey. 30 patients in one shot dilation (OSD) group.The mean age was 39.5 years. Control group of 30 patients were included in standard PCNL procedure where method of tract dilation was done by regid Amplatz dilators. Access time and fluoroscopy time in OSD group was approximately shorter. Statistically it was significant. Successful dilation and stone free rate were subsequently 98% and was significant. Data collected included patient access time, radiation exposure, total operating time, preoperative and postoperative hemoglobin concentrations, tract dilatation failures, complications and transfusions. Conclusion: The use of one shot and standard prone position under general anaesthesia combines the advantages of these both methods including less radiation exposure and shorter access and operative time. One shot dilation technique is safe, economical and feasible technique with added advantage,lesser radiation exposure and lesser chance of blood transfusion.

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.

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.
