The Journal of Urology, 2012Co-Authors: Andrew Fuller, Hassan Razvi, John D Denstedt, Linda Nott, Margaret S Pearle, Furio Cauda, Damien M Bolton, A Celia, Jean J.m.c.h. De La RosetteAbstract:Purpose: In addition to more commonly forming stones, obese patients present a number of challenges when undergoing percutaneous Nephrolithotomy. We evaluated percutaneous Nephrolithotomy outcomes in 3,709 patients stratified by body mass index.Materials and Methods: A prospective database administered by CROES (Clinical Research Office of the Endourological Society) captured data on 5,803 patients treated with percutaneous Nephrolithotomy between November 2007 and December 2009. Patients with known solitary kidney, previous percutaneous Nephrolithotomy and congenital abnormalities were excluded from analysis. For statistical analysis patients were categorized as normal weight—body mass index 18.5 to 25 kg/m2, overweight—25 to 30, obese—30 to 40 and super obese—greater than 40.Results: During the study period 5,803 patients underwent percutaneous Nephrolithotomy, of whom 3,709 met the inclusion criteria. As expected, obesity was associated with significantly higher rates of comorbid conditions and anticoa...

prevention and treatment of complications following percutaneous Nephrolithotomy
Current Opinion in Urology, 2008Co-Authors: Andreas Skolarikos, Jean J.m.c.h. De La RosetteAbstract:PURPOSE OF REVIEW: The aim of this article is to identify classification and grading systems of percutaneous Nephrolithotomy-related complications and evidence for the prevention and treatment of these complications. RECENT FINDINGS: A total complication rate of up to 83% following percutaneous Nephrolithotomy was recognized. These complications were mostly clinically insignificant including minor bleeding or fever. The frequency of major complications was 0.9-4.7% for septicemia, 0.6-1.4% for renal hemorrhage requiring intervention, 2.3-3.1% for pleural injury and 0.2-0.8% for colonic injury. The significance of grading perioperative complications according to their severity, emphasizing the need for a unique and broadly accepted classification system, which could be helpful for monitoring and reporting outcomes emerged from the current review. The modified Clavien system has recently been used for this purpose. Proper patient selection, preoperative imaging for planning the operation, adequate antibiotic prophylaxis and therapy, manipulation of the collecting system only under fluoroscopic or endoscopic control, use of a continuous flow system, use of normal saline as irrigant fluid, judicious stone fragmentation and finally fluoroscopic monitoring of nephrostomy tube insertion and removal are necessary to prevent percutaneous Nephrolithotomy complications. Appropriate treatment has been sufficiently described in the literature. SUMMARY: Currently, a high index of suspicion and prompt recognition and institution of appropriate treatment of percutaneous Nephrolithotomy-related complications is fundamental to limit morbidity

risk factors for postoperative complications of percutaneous Nephrolithotomy at a tertiary referral center
The Journal of Urology, 2015Co-Authors: Daniel Olveraposada, John D Denstedt, Linda Nott, Thomas Tailly, Husain Alenezi, Philippe D Violette, Hassan RazviAbstract:Purpose: We sought to describe and evaluate the complications related to percutaneous Nephrolithotomy and identify risk factors of morbidity according to the modified Clavien scoring system. We also sought to specify which perioperative factors are associated with minor and major complications.Materials and Methods: We retrospectively analyzed data on patients who underwent percutaneous Nephrolithotomy from 1990 to 2013. Descriptive statistics were used to analyze patient characteristics, medical comorbidities and perioperative features. Complications were categorized according to the Clavien score for percutaneous Nephrolithotomy. The Mann-Whitney and Fisher exact tests were used as appropriate. Logistic regression analysis was performed to look for prognostic factors associated with major complications.Results: A total of 2,318 surgeries were evaluated. Mean age of the population was 53.7 years. The stone-free rate at hospital discharge was 81.6%. The overall complication rate was 18.3%. Two deaths occu...

Effect of Medical Management on Recurrent Stone Formation Following Percutaneous Nephrolithotomy
Journal of Urology, 2007Co-Authors: David E. Kang, Michaella M. Maloney, George E. Haleblian, W. Patrick Springhart, Emily Honeycutt, Eric L. Eisenstein, Charles G. Marguet, Glenn M. PremingerAbstract:Purpose: Percutaneous Nephrolithotomy is a commonly used procedure for treatment of large or complex renal calculi. In some instances postoperative residual stone fragments are an unavoidable result. Yet to our knowledge no study has examined the impact of medical management on stone formation in patients with or without residual fragments following percutaneous Nephrolithotomy. Thus, we have conducted the first investigation of aggressive medical management following percutaneous Nephrolithotomy and its impact on stone formation rates in patients with and without residual fragments.Materials and Methods: A total of 70 patients who underwent percutaneous Nephrolithotomy and received counseling regarding selective medical management following a comprehensive metabolic evaluation, were identified. Patients were placed into 4 groups following percutaneous Nephrolithotomy, that is stone-free or residual fragments, who underwent or did not undergo medical therapy. New stone formation was assessed by spontaneou...

Percutaneous Nephrolithotomy in Paediatric Population: A Single Center Experience.
Journal of Nepal Health Research Council, 2020Co-Authors: Mahesh Bahadur Adhikari, Sumeet Karna, Kinju Adhikari, Jagdish Lal BaidyaAbstract: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.

Impact of Miniaturization on Early Outcome of Percutaneous Nephrolithotomy.
Journal of Nepal Health Research Council, 2019Co-Authors: Mahesh Bahadur Adhikari, Sumeet Karna, Kinju Adhikari, Atul Kasaju, Jagdish Lal BaidyaAbstract:BACKGROUND Percutaneous Nephrolithotomy has become the standard procedure for large renal stones but still remains highly challenging due to complications such as bleeding and sepsis, even though it has high stone free rate (SFR). We report the early outcomes of more than 1000 percutaneous Nephrolithotomys done in our center. METHODS A retrospective study of all patients undergoing percutaneous Nephrolithotomy from January 2010 to December 2017 in single institution was conducted. All cases were stratified into three groups based on tract size; standard percutaneous Nephrolithotomy with tract size ? 22 F, mini percutaneous Nephrolithotomy with tract size 15 - 20 F and ultramini percutaneous Nephrolithotomy with tract size ? 14 F. Age, gender, stone complexity using Guy's stone score, stone size, operative time, hemoglobin drop, hospital stay, early major and minor complications were reviewed. RESULTS A total of 1074 patients had undergone percutaneous Nephrolithotomy among which, 578 patients were standard percutaneous Nephrolithotomy, 433 mini percutaneous Nephrolithotomy and 63 had undergone ultramini percutaneous Nephrolithotomy. There was even distribution of patients with Guy's stone score 1 and 2 in all three groups. However, majority of patients with Guy's stone score 3 underwent standard percutaneous Nephrolithotomy or mini percutaneous Nephrolithotomy and no patients with Guy's stone score 4 underwent ultramini percutaneous Nephrolithotomy. Age group, gender and operative time were comparable between the groups; however, significant difference was noted in terms of less hemoglobin drop and shorter hospital stay (p-value < 0.05) in the miniaturized percutaneous Nephrolithotomy group. Complications were found to be fewer in mini percutaneous Nephrolithotomy and ultramini percutaneous Nephrolithotomy group in comparison to standard percutaneous Nephrolithotomy. CONCLUSIONS Miniaturization of tract size significantly decreases post-operative complication rates, blood loss and hospital stay while maintaining high stone free rates in well selected patients undergoing Percutaneous Nephrolithotomy.

Safety and Efficacy of Bilateral Simultaneous Percutaneous Nephrolithotomy
Journal of Nepal Health Research Council, 2019Co-Authors: Mahesh Bahadur Adhikari, Sumeet Karna, Atul KasajuAbstract: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.
