Salvage Percutaneous Nephrolithotomy: Analysis of Outcomes following Initial Treatment Failure
Journal of Urology, 2016Co-Authors: Michael S. Borofsky, Dean G. Assimos, Daniel A. Wollin, Thanmaya Reddy, Ojas Shah, James E. LingemanAbstract:Purpose Percutaneous Nephrolithotomy has high potential for morbidity or failure. There are limited data regarding risk factors for failure and to our knowledge no published reports of surgical outcomes in patients with prior failed attempts at Percutaneous stone removal. Materials and Methods We identified patients referred to 3 medical centers after prior failed attempts at Percutaneous Nephrolithotomy. A retrospective chart review was performed to analyze reasons for initial failure and outcomes of salvage Percutaneous Nephrolithotomy. Outcomes were compared to those in a prospectively maintained database of more than 1,200 patients treated with a primary procedure. Results Salvage Percutaneous Nephrolithotomy was performed in 31 patients. Unsuitable access to the stone was the reason for failure in 80% of cases. Other reasons included infection, bleeding and inadequate instrument availability in 6.5% of cases each. Compared to patients who underwent primary Percutaneous Nephrolithotomy those treated with salvage were more likely to have staghorn calculi (61.3% vs 31.4%, p

Percutaneous Nephrolithotomy directlythrough an angiomyolipoma
Urology, 1994Co-Authors: Bradley P. Kropp, Mark D. Dabagia, John Scott, James E. LingemanAbstract:Abstract We present a patient with tuberous sclerosis and bilateral angiomyolipomaswith a right partial staghorn calculi in which the calculi was managed with a Percutaneous Nephrolithotomy. Despite the inherent risk of hemorrhage with a Percutaneous approach compounded by the fact that this was done directly through a tumor, we were able to render the patient stone free with no intraoperative bleeding, complications, or the need for postoperative blood transfusion. To our knowledge, this is the first reported case of Percutaneous Nephrolithotomy directly through a renal angiomyolipoma.

the croes Percutaneous Nephrolithotomy global study the influence of body mass index on outcome
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...

tubeless Percutaneous Nephrolithotomy the new standard of care
The Journal of Urology, 2010Co-Authors: Dorit E Zilberman, Charalampos Mamoulakis, Michael N Ferrandino, Michael E Lipkin, Jean J.m.c.h. De La Rosette, M. Pilar Laguna, Glenn M. PremingerAbstract:Purpose: Traditionally the placement of a nephrostomy tube at the conclusion of Percutaneous Nephrolithotomy is considered the standard of care. However, the need for nephrostomy tube placement has been questioned by numerous authors. We evaluated the literature regarding tubeless Percutaneous Nephrolithotomy, and determined potential candidates for tubeless Percutaneous Nephrolithotomy and whether this procedure can be considered the new standard of care for complex stone removal.Materials and Methods: A MEDLINE® search was conducted between May 1997 and January 2010 to detect studies reporting tubeless Percutaneous Nephrolithotomy. “Nephrolithiasis,” “Percutaneous Nephrolithotomy,” “tubeless” and “lithotripsy” were used as medical subject headings (MeSH) key words. Additional citations were identified by reviewing the reference lists of the included articles. All relevant articles were reviewed for indications, outcomes and complications.Results: The data obtained from 50 reports document comparable com...

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

Percutaneous Nephrolithotomy and its legacy
European Urology, 2005Co-Authors: Andreas Skolarikos, G Alivizatos, Jean J.m.c.h. De La RosetteAbstract:Abstract Objective: We review the indications of Percutaneous Nephrolithotomy (PNL), its safety and efficacy when applied to various patient groups as well as the different points of technique, giving emphasis on new tips and ongoing debates. Methods: A literature search was performed using MEDLINE database on PNL between 1980 and 2004. Results: Percutaneous Nephrolithotomy (PNL) has been successfully and safely used to treat patients with renal stones for more than a quarter of a century. Still, the use of PNL in treating renal stones in different patient groups, such as children, obese patients, patients with renal congenital anomalies, patients who had previous open renal surgery and patients who have undergone renal transplantation are always of high interest. Simultaneous bilateral Percutaneous Nephrolithotomy seems to have a certain role in treating bilateral renal stones, especially when proficiency is achieved for unilateral PNL. Various aspects of the procedure such as patient positioning, renal access, the ideal dilating method, the type of nephrostomy tube used, as well as the actual need for drainage, have been debated. Conclusion: PNL is currently the procedure of choice for removal of large renal calculi. The need for well designed prospective randomized trials comparing PNL with alternative treatment modalities arises through the literature review.

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...
