Introduction: Dilation of the track can be achieved by multiple incremental flexible Amplatz type, Alken metal telescoping dilators, or balloon in Percutaneous Nephrolithotomy (PCNL). Balloon dilator is the most expensive method. Both of the incremental dilation techniques are more time consuming with higher failure rates. Hence, a prospective randomized study was conducted to compare the safety and efficacy of “single shot” dilation of the nephrostomy tract by amplatz dilator with serial alken metallic telescopic dilation technique in PCNL. Methods: Of the 138 renal stone patients who underwent PCNL from January 2015 to December 2015, 100 patients were randomized into two groups. Serial tract dilation with alken metallic dilators was used in group A (n=50), and one shot dilation technique in Group B (n=50). The access tract dilation time, success rate, blood loss and complications were evaluated. Results: Both the groups were comparable in terms of mean age, location and size (largest diameter) of the stone (p>0.05). No difference was observed in the procedural success rate between groups A and B (96% v 94% respectively, p=0.64). Mean access time was similar in both groups (5.89+2.67 vs 4.98+2.0 mins, p=0.06). Complications between the groups were not significantly different. There were 6 patients with previous open stone surgery in both the groups. Previous open stone surgery did not impact procedural success rate, access time and complications in both groups. Conclusion: One-shot dilation technique is equally as effective, safe and well tolerated as metal telescopic dilation techniques even in patients with history of ipsilateral open stone surgery.

Background: Nephrolithiais is a recurrent disease. Recent advances have enabled stone surgeries to be performed by minimal invasive techniques; but still a large number of patients present with history of ipsilateral open renal stone surgery. Previous scar to the kidney and overlying muscles are fraught with possibility of increased complications. This study was conducted to evaluate the perioperative results of percutaneous nephrolithotomy in patients with a history of open stone surgery and to compare with those undergoing percutaneous nephrolithotomy for the first time.Methods: A retrospective study of all the percutaneous nephrolithotomy performed by standard technique within four years at Bir Hospital was made. Patients were divided into those undergoing percutaneous nephrolithotomy for the first time and those who had undergone open renal stone surgery in the past. Preoperative and intraoperative variables were recorded and postoperative stone free status and complications were evaluated. Results: Six hundred and twenty seven patients; out of 691, who had undergone percutaneous nephrolithotomy were included. Demographic variables and stone characteristics were similar in the two study groups. percutaneous nephrolithotomy was found to be statistically similar in the two groups in terms of the number of tracts made (p= 0.1642) and operative time (0.9197). Exit strategies were similar in both groups. Stone free rate was 83.33% in patients undergoing percutaneous nephrolithotomy for first time and 82.08% in those with history of open surgery. Average hospital stay was 3 days in both groups. Although the group with history of previous surgery had significantly more complications (p= 0.0207), Clavien grading was similar in the two groups.Conclusions: This study shows that the rate of complications is more in patients with history of open surgery, most complications are minor, not requiring intensive management. percutaneous nephrolithotomy is efficient and safe in patients with history of open renal stone surgery.

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: Renal pelvic squamous cell carcinoma is a very rare tumor, with a prevalence <1% of all urinary tract tumors, about 0.5–8% of all kidney tumors, and the average age is 50–70 years. Although the incidence of renal squamous cell carcinoma is less common than renal cell carcinoma and renal transitional cell carcinoma, due to its more aggressive nature renal squamous cell carcinoma is often found intraoperatively and is already in an advanced stage or metastasis. The relevant medical history of squamous cell carcinoma is pyelonephritis, chronic nephrolithiasis, and a history of kidney stone surgery. Data which was obtained from previous research at Hasan Sadikin Hospital, from January 2014–December 2017, found the incidence of renal squamous cell carcinoma from nephrectomy procedures was 6%. Methods: This study was a cross-sectional study with a correlative analytic study, samples were taken consecutively from biopsy of kidney mucosa intraoperatively in hospitalized patients with kidney stones with size larger than 20 mm at the Department of Urology, Hasan Sadikin Hospital Bandung, which performed open kidney surgery or percutaneous nephrolithotomy from January–May 2019. Results: The number of samples in this study were from 30 patients, consisting of 16 males and 14 females. Five patients underwent open kidney surgery and 25 patients underwent percutaneous nephrolithotomy surgery, with an average of age of 49.5±11.8 years and 63.3% of patients were aged from 40–60 years. In this study, one patient (3.3%) showed squamous cell carcinoma of the kidney, a 57-year-old male patient with a left staghorn kidney stone who underwent left percutaneous nephrolithotomy surgery. Conclusion: There is a benefit for intraoperative kidney mucosal biopsy as a screening for squamous cell carcinoma of the kidney in nephrolithiasis patients with stones larger than 20 mm. Level of evidence: 3

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We collected data from medical record between January 2000 and December 2015. A total of 345 primary percutaneous nephrolithotomy procedures were performed for patients with staghorn calculi. This study included both and made no distinction between partial and complete staghorn calculi. Stone-free is defined as the absence of residual stones after undergoing percutaneous nephrolithotomy for the first time. Significant factors from univariate analysis that correlated with stone-free rate after primary percutaneous nephrolithotomy of staghorn stone were further analyzed using multivariate regression analysis. Results: The mean patient age was 52.23±10.38 years. The stone-free rate of percutaneous nephrolithotomy monotherapy was 62.6%. The mean operating time was 79.55±34.46 minutes. The mean length of stay in hospital was 4.29±3.00 days. Using the chi-square test, history of ipsilateral open renal stone surgery (p = 0.01), stone burden (p = < 0.001), and type of anesthesia (p = 0.04) had a significant impact on the stone-free. From multivariate analysis, the history of ipsilateral open renal stone surgery [OR 0.48; 95% CI 0.28-0.81; p 0.01] and the stone burden [OR 0.28; 95% CI 0.18-0.45; p 0.00] were significant independent risk factors for stone-free.

Background: Prolonged urinary leakage after nephrostomy tube removal leads to increased morbidity of PCNL and increased hospitalization. Objective: To evaluate factors affecting post nephrostomy removal urinary leakage after percutaneous nephrolithotomy. Patients and Methods: One hundred eight (108) patients older than 18 years who underwent PCNL were studied prospectively. The reasons that can affect urinary leakage postoperatively were divided into 4 categories according to individual factors including age, gender, and body mass index; Renal factors; including, previous operation, history of ESWL, parenchymal cortical thickness, and grades of hydronephrosis; stone factor (stone burden); and surgical factors including the number of tracts, presence of double J stent, nephrostomy tube diameter and stay duration. These data were compared for postoperative urine leak. Results: Urinary leakage was revealed in 76 of 108 patients (70.3%). There was no statistically significant relationship between individual factors and urinary leakage (P >0.05). Among renal factors, just parenchymal cortical thickness and grade of hydronephrosis were strongly related to the urinary leakage (P <0.001). The renal stone burden did not affect urinary leakage (P >0.05). Among surgical factors, placing of ureteral double-J stent highly minimized the incidence of urinary leakage (P<0.001), and the urinary leakage significantly correlated with the increased diameter of the nephrostomy tube and staying duration (P<0.05). Conclusion: After PCNL surgery, some factors show to influence post-PCNL urinary leakage. however most of the urinary leakage was treated conservatively, but it increases morbidity and hospitalization.
