Objective: To identified outcomes and complications of percutaneous nephrolithotomy (PCNL) in patients of various body mass indices (BMI) to determine the safety of this procedure in patients with elevated BMI.Material & methods: The analytic observational prospective study of patients who underwent PCNL between February to July 2015 in the operating room Soetomo General Hospital Surabaya. Specifically, BMI, stone-free rates, difficulties duringsurgery, complications, and Clavien score were assessed. We evaluate the independent contribution of BMI as a predictor of outcomes. Results: There were 35 selected patients with kidney stone and planned to PCNL, 20 patients were included and 15 patients were excluded from this study. The patients consisted of 10 men (50%) and 10 women (50%). Mean age was 47.55 years (range 33-75). There were 4 patients with diabetes (20%), and 10 patients with hypertension (50%). Mean stone size was 23.30 mm. Stone location was 11 patients (55%) in the right kidney, and 9 patients (45%) in the left. There were 12 patients (60%) with a single stone, and 8 patients (40%) with multiple stones. BMI values were distributed as follows,underweight 1 patient (5%), normoweight 7 patients (35%), overweight 6 patients (30%), obesity 6 patients (30%). Mean skin to stone distance (SSD) was 87.56 mm. Stone free rate was 55%, and difficulties during surgery only seen in 1 patient (5%) bleeding profusely and open surgery was performed. Clavien score in these patients were grade I in 11 patients (55%), grade II in 7 patients (35%), and grade IIIB in 2 patients (10%). The BMI had no significant effect with Intra operative and postoperative difficulties (0.390. p <0.05. CI 95%). However the lower stone free rate had significant effect (0.040. p <0.05. CI 95%).Conclusion: BMI had no significant effect with Intraoperative and postoperative difficulties in PCNL.However, the lower stone-free rate risk associated with elevated BMI was significant.

Background: Urolithiasis is one of the common diseases of the urinary system, with an incidence of approximately 5-10% among the general population. Among the minimally invasive surgeries, percutaneous nephrolithotomy (PCNL) is the gold standard therapy for large and/or complex renal stones. Objective: The study was carried out to predict the stone-free rate after PCNL by using the Guy's stone score. Methods: This prospective cross-sectional study was conducted in the Department of Urology, Bangabandhu Sheikh Mujib Medical University, (BSMMU), Dhaka from February 2016 to January 2017. The patients with renal stone attending the outpatient department who met the criteria of standard PCNL. Results: Atotal of 52 patients with renal stone were included in this study.  The mean age was to be found 45.3±14.0 with range of 18 to 73 years. Male to female ratio was 3.3:1. Almost three fourth (74.5%) patients had normal body mass index. All patients had normal anatomy. More than half 27 of the (51.9%) patients had found grade I, 10 (19.2%) Grade II, 11(21.2%) Grade III and 4 (7.7%) Grade IV. Nearly two third 34 (65.4%) patients were found total stone cleared and 18(34.6%) had residual stone. Cleared stone was found 23(85.2%) in grade I, 7(70.0%) grade II, 3(27.3%) in grade III and 1(25.0%) in grade IV. Conclusion: Based on the study findings, it may be concluded that higher the GSS less the stone free rate.It will help in better patient counseling preoperatively, and to predict the need for ancillary treatment.

Abstract Purpose: To evaluate the aspects affecting transfusion following percutaneous nephrolithotomy (PCNL).Background: From 2016 to 2019, 665 patients underwent PCNL for removal of renal calculi in our center. Complications, including hemorrhages, have been reported. Twenty-three patients (3.5%) have received a blood transfusion and twelve (1.9%) were treated by hyper-selective embolization. We focus on the influencing factors related to postoperative blood transfusion. The factors analyzed were (age, sex, hypertension, diabetes, serum creatinine level, preoperative hemoglobin, and use of anticoagulants or antiplatelet medications); renal and stone factors (previous surgery, abnormal anatomy, stone side, stone burden, stone type); and surgical features: (access number, the calyx of puncture and stone-free rate). These data were analyzed for the presence of bleeding.Results: Among individual factors, preoperative hemoglobin level (P<0.001), and urinary infection (P<0.001) were significantly correlated with blood transfusion. Among renal and stone factors, only previous history of open surgery was significantly correlated with blood transfusion (P<0.05). Stone type or stone burden does not correlate with transfusion. There was also no statistically significant correlation between surgical features and bleeding, and a lower stone-free rate reported for transfusion group.Conclusion: The obtained results demonstrated that PCNL is a safer surgery in a high volume center, but anemic conditions, infections and history of open surgery will significantly increase transfusion rate following PCNL.

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.

Background: To evaluate the safety and efficacy of bilateral simultaneous percutaneous nephrolithotomy in one tertiary hospital in Nepal.Methods: Retrospective study was done for all patients that underwent bilateral simultaneous percutaneous nephrolithotomy in our center from January 2010 to December 2017. The study included 36 male and 16 female patients with totalof 104renal units at an average age of 37 years (range 3 -65 years). Five patients were planned for bilateral simultaneous Percutaneous nephrolithotomy, but intraoperatively the procedure was aborted after completion of only one side due to various factors. All PCNL were performed in prone position under general anesthesia.Results: In91.2% of the patients, bilateral simultaneous percutaneous nephrolithotomy could be performed as planned. Average time required for bilateral simultaneous percutaneous nephrolithotomy was 94 ± 38.8mins (range 25 – 170 mins) with average hemoglobin drop of 1.85 ± 1.30gm% (range 0.1 - 4.2gm%) and no significant change in serum creatinine levels. Multiple access tracts (>1) had to be created in 3 renal units. Most of the renal stones were Guy’s stone score (GSS) 1 and 2 whereas 15.4% were GSS of 3 and 4.Overall stone free rate was 94% with significant residual stones (>4mm) in 6 renal units which were subjected to extracorporeal shockwave lithotripsy (SWL) on a later date (Clavien-Dindo Grade: III-a). Bladder clot evacuation was done in one patient (Clavien-Dindo Grade: III-b). Blood transfusion was required in two patients and two patients developed postoperative sepsis (Clavien-Dindo Grade: II). One patient developed hydrothorax which was managed successfully (Clavien-Dindo Grade: III-a). Conclusions: Bilateral simultaneous Percutaneous nephrolithotomy is feasible and safe procedure, given that the patients are appropriately selected based upon Guy’s stone score, stone burden, pelvi-calyceal anatomy and overall health status.Keywords: Bilateral simultaneous;endourology; percutaneous nephrolithotomy; urolithiasis.

Introduction: Since its introduction in 1976, percutaneous renal stone surgery has undergone several modifications. Reduction in size of access sheath was one of them which was first reported by Jackman in 1998. The miniaturisation of access sheath in Mini-Percutaneous Nephrolithotomy surgery has significantly reduced the intervention related morbidity with similar outcome as of standard Percutaneous Nephrolithotomy. Methods: This is a prospective cohort study where a single surgeon without previous experience of independent PCNL surgery performed Mini PCNL under controlled condition for renal stone sized 10 to 30 mm. The outcome was measured in terms of stone free rate and postoperative complications. The association of stone free rate and drop in haemoglobin level with different preoperative and operative variables were calculated with Pearson’s correlation test and p value <0.05 was considered significant. Results: Mini PCNL was performed in total of 63 renal units. The mean age was 37.8 ± 9.9 years with male: female ratio of 1.8:1. The average stone size was 16.8 ± 2.9 mm. The mean operative time was 55.2 ± 19.0 (30-110) minutes. The stone free rate was 98.2 ± 3.6 %. The mean drop in haemoglobin was 1.3 ± 0.8 and blood transfusion rate was 4.7%. The average hospital stay was 2.6 ± 1.3 days. The grade I complications was 15.8% and grade II and III was 7.9% each. Stone free rate was significantly associated with stone number (r = -0.47, p = 0.004). Similarly fall in haemoglobin was associated with total operative time (r = 0.49, p = 0.003). The stone size, hardness of stone (HU) and size of access sheath had no significant association with stone free rate and fall in haemoglobin. Conclusions: Mini PCNL is as effective as standard PCNL with higher safety margin in small and medium size stone (10 to 30 mm) during learning curve of endo-urology procedure.

Background: Management of paediatric stone disease is challenging as they are considered high risk group. Percutaneous nephrolithotomy is minimally invasive procedure with definite advantages in terms of higher stone clearance in single session and no long term effect in renal function.Methods: Retrospective study was done including all patients upto the age of 18 years who underwent Percutaneous nephrolithotomy from January 2010 to December 2018 in our center after taking approval from ethical committee. Data was collected regarding gender, operative side, operative time duration, hospital stay, post-operative decrease in hemoglobin, stone size, Guy’s stone score and early post-operative complications with Clavien-Dindo grade.Results: Percutaneous nephrolithotomy was done in 48 renal units in 44 patients. 28 patients were boys and 16 were girls with mean age of 10.91 ± 5.22 years and mean stone size 17.16 ± 6.43 mm. 91.6% of cases had Guy’s stone score of 1 and 2. Standard percutaneous nephrolithotomy was done in 21 renal units, mini percutaneous nephrolithotomy in 24 renal units and supermini percutaneous nephrolithotomy was done in three renal units with total stone free rate of 93.4%. Three patients required extracorporeal shockwave lithotripsy for significant residual stone. Average post-operative hemoglobin drop was 1.2 gm%. Overall complications rate was 18.1% with 4.5% of complications being grade 1 and 2 whereas 13.6% were Grade 3.Conclusions: Percutaneous nephrolithotomy is safe and feasible in paediatric patients with large stone burden, complex anatomy or shock-wave lithotripsy failure with acceptable complication and stone free rate.

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.
