Shock Wave Lithotripsy in Pediatric Stone Disease: A 15-Year Single-Center Experience with 2 Types of Lithotripters.

Introduction And Objectives: We report our experience with pediatric shock wave lithotripsy (SWL) using two types of lithotripters: Dornier HM3 (HM3) and Dornier Lithotripter SII (DLS).

Study Design: We retrospectively reviewed the charts of children who underwent SWL between 2002 and 2016. Patients were divided into two groups based on the type of the lithotripter: during 2002-2009, we used the electrohydraulic HM3 lithotripter which was replaced in 2009 with the DLS electromagnetic lithotripter.

Laparoscopic Nephrectomy: Initial Case Report.

A tumor-bearing right kidney was completely excised from an 85-year-old woman using a laparoscopic approach. A newly devised method for intra-abdominal organ entrapment and a recently developed laparoscopic tissue morcellator made it possible to deliver the 190 gm. kidney through an 11 mm.

Differences in renal stone treatment and outcomes for patients treated either with or without the support of a ureteral access sheath: The Clinical Research Office of the Endourological Society Ureteroscopy Global Study.

Purpose: To describe the differences in the treatment and the outcomes of renal stones treated with flexible ureteroscopy (URS) either with or without the support of a ureteral access sheath (UAS).

Methods: The Clinical Research Office of the Endourological Society URS Global Study involved the collection of prospective data from consecutive patients treated with URS at centers around the world over a 1-year period. Baseline characteristics, stone location, treatment details, postoperative outcomes and complications were recorded.

Obstructive uropathy caused by retroperitoneal fibrosis presents as a late manifestation of sarcoidosis.

Obstructive uropathy in sarcoidosis can result from retroperitoneal involvement, retroperitoneal fibrosis (RPF), renal stones, or ureteral involvement. We report acute kidney injury (AKI) from obstructive uropathy because of RPF in a female patient, 2 years following the resolution of pulmonary sarcoidosis. We propose that RPF may occur in sarcoidosis even when a lag of years separates the presentations of the illnesses.

What happened to shockwave lithotripsy during the past 22 years? A single-center experience.

Introduction: From 1985 to August 2007 we have performed 15,324 shockwave lithotripsy (SWL) treatments using the Dornier HM3 lithotripter. We studied trends in the characteristics of treatments and patients.

Patients And Methods: Patient data were recorded in a computerized database.

Fever after shockwave lithotripsy--risk factors and indications for prophylactic antimicrobial treatment.

Purpose: To identify risk factors for fever after shockwave lithotripsy (SWL) and suggest guidelines for prophylactic antimicrobial treatment.

Patients And Methods: Between 1985 and 2007, a total of 15,324 SWL procedures were performed in our institution using the Dornier HM3 lithotripter. Because stone analyses were not available in the majority of patients, management of stones larger than 2 cm in diameter were excluded from this analysis to minimize the ratio of struvite stones as a possible cause for postprocedural fever.

Extracorporeal shock wave lithotripsy in prepubertal children: 22-year experience at a single institution with a single lithotriptor.

Purpose: The sophistication of percutaneous nephrolithotomy and ureteroscopy challenges the efficacy of ESWL for urolithiasis in prepubertal patients. We evaluated our long-term experience with ESWL in these patients and determined its efficiency.

Materials And Methods: We retrospectively reviewed the charts of all prepubertal patients who underwent ESWL.

Perioperative morbidity and mortality in 80 years and older undergoing elective urology surgery - a prospective study.

Background And Purpose: The number of octogenarians requiring surgery increases constantly. Data regarding perioperative morbidity and mortality in octogenarians is limited. Our aim was to assess surgery-related complications in octogenarians, undergoing urological surgery.

Inflamation of the testis and epidididymis in an otherwise healthy child: is it a true bacterial urinary tract infection?

Purpose: The exact etiology of acute gonadal inflamation (EO) in children is unknown. Bacterial infection and underlying urological abnormalities are thought to be the main causes, and hence antibiotic treatment and further invasive urinary tract imaging studies are usually recommended. The purpose of this study was to assess the role of bacterial infection in pediatric acute EO.

Role of bone regeneration and turnover modulators in control of fracture.

Although most fractures heal in accordance with a highly regulated and well-known multistep process, 5%-10% of fractures result in delayed union or nonunion, causing morbidity, prolonged hospitalization, and economic cost for the individual and society. Ongoing research has improved our understanding of genes and molecules that are expressed during fracture healing. This knowledge has been translated into preclinical/clinical trials.

Hemorrhagic complications of minimally invasive urological surgeries, treated with selective endovascular embolization.

Minimally invasive urological procedures have gained in popularity and replaced open surgery in various urological procedures. Although considered minimally invasive, these procedures are not free from complications, and life-threatening hemorrhage may occur. Herein we describe 3 case series of patients who underwent minimally invasive urological surgeries that were complicated with bleeding.

Antegrade pyelography versus unenhanced multidetector CT in the assessment of urinary-tract stones after percutaneous nephrostomy insertion: a prospective blinded study.

Background And Purpose: In patients with a percutaneous nephrostomy tube (PCN) inserted for symptomatic stone disease, antegrade pyelography is an accepted modality to assess the collecting system and residual stone status prior to PCN removal. Recently, unenhanced multidetector CT (UMDCT) has shown its superiority for the assessment of urinary-tract stones. Comparison of UMDCT with antegrade pyelography has never been done; hence, our aim was to compare the two methods for the assessment of urinary stones in patients with a PCN.

Shock wave lithotripsy for ureteral stones in elderly male patients.

Introduction: Age has never been considered as a factor in the treatment of ureteral stones, but elderly male patients may suffer from concomitant illnesses that may affect SWL results, such as voiding difficulties and musculo-skeletal and cardio-vascular disorders. The aim of this study was to assess the success rate and complications of shock wave lithotripsy (SWL) for all size and location ureteral stones in patients older than 70 years of age.

Patients And Methods: We retrospectively reviewed the charts and radiology films of all patients who had undergone SWL for ureteral stones with the HM3 lithotriptor and compared the results of patients younger than 70 years to those older than 70 years.

Extracorporeal shock wave lithotripsy for large ureteral stones using HM3 lithotriptor.

Purpose: We assessed the efficacy of extracorporeal shock wave lithotripsy for large (more than 10 mm) ureteral calculi with the unmodified Dornier HM3 lithotriptor.

Materials And Methods: A total of 96 consecutive patients with large ureteral stones were treated with shock wave lithotripsy using an unmodified HM3 lithotriptor. Patients, stone characteristics, preliminary treatment before shock wave lithotripsy, additional procedures after shock wave lithotripsy, complications and clinical outcomes were assessed.

A review on hematuria in children.

Asymptomatic hematuria is very common in pediatric and adolescent patients. In contrast to painless hematuria in adults, the differential diagnosis and investigative modalities in the pediatric population is vastly different. This article presents the major diseases that may cause hematuria in children and suggests an evaluation algorithm for the pediatric urologist.

[Hematuria in children].

A symptomatic hematuria is very common in pediatrics and adolescence. In contrast to painless adult hematuria, the differential diagnosis and investigative modalities in the pediatric population is vastly different. This article presents the major diseases that may cause hematuria in children and suggests an evaluation algorithm for the pediatric urologist.

[Shock wave lithotripsy for ureteral stones--single institute experience in 661 consecutive cases].

Introduction: Optimal treatment for ureteral stones is still controversial. The main retreatment options include ureteroscopy and shock wave lithotripsy (ESWL). The study aimed to assess the efficacy of ESWL using the unmodified HM3 lithotripter (Dornier Medical Systems) to achieve stone-free status in patients with ureteral calculi, regardless of stone size and location along the ureter.

Urothelial cancer of the renal pelvis in percutaneous nephrolithotomy patients.

Introduction: The association between staghorn calculus of the kidney long-standing and urothelial tumors of the renal pelvis is well documented. We describe 3 patients with urothelial cancer in a kidney who underwent percutaneous nephrolithotomy (PCNL).

Patients And Methods: Retrospective analysis of our series of more than 500 PCNLs revealed 3 patients in whom urothelial cancer of the renal pelvis was diagnosed during or following percutaneous stone removal.

Safety and efficacy of extracorporeal shock wave lithotripsy in infants.

Purpose: Extracorporeal shock wave lithotripsy (ESWL) in older children appears to have comparable results when compared to adults, no study has focused on its use in younger children. We reviewed our ESWL experience in children under age 3.5 years to evaluate its safety, and define optimal treatment parameters.

Outcome analysis of tunica vaginalis flap for the correction of recurrent urethrocutaneous fistula in children.

Purpose: Urethrocutaneous fistula is the most common (2% to 10%) complication of hypospadias surgery. The correction of such fistula is associated with a 10% to 40% failure rate. The key measure to ensure a successful repair is separation of the suture lines in the urethra and skin, using well vascularized elastic tissue.

Inverse relationship between Skp2 ubiquitin ligase and the cyclin dependent kinase inhibitor p27Kip1 in prostate cancer.

Purpose: Prostate carcinomas show a low level of the cell cycle inhibitor p27, which correlates with tumor aggressiveness. In tumors p27 is of the WT species and its deregulation is due to aberrant ubiquitin mediated degradation. The p27 is degraded following phosphorylation and subsequent recognition by SCFSkp2 ubiquitin ligase.

Interleukin-2, interferon-alpha, 5-fluorouracil, and vinblastine in the treatment of metastatic renal cell carcinoma: a prospective phase II study: the experience of Rambam and Lin Medical Centers 1996-2000.
