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.

Long-term Results of Ventral Penile Curvature Repair in Childhood.

Objective: To assess the postpubertal outcome of ventral penile curvature repaired in infancy in terms of recurrence and aesthetics.

Materials And Methods: Postpubertal patients treated for hypospadias and ventral penile curvature in infancy at a tertiary medical center were invited to undergo assessment of the quality of the repair. Findings were compared between patients with a straight penis after skin release and patients who required dorsal plication.

Pyogenic Granuloma: Possible Cause for Macroscopic Hematuria in Children.

Pyogenic granuloma (PG) is a benign, vascular tumor that is rarely reported in the urinary tract of pediatric population. Herein we present a case of a child followed up for recurrent painless macroscopic hematuria. We performed ureteroscopy, and a whitish lesion was discovered in the upper calyx of the right kidney.

Percutaneous nephrolithotomy for infection stones: what is the risk for postoperative sepsis? A retrospective cohort study.

The purpose of this study was to compare the postoperative course of patients with positive stone culture (SC) to patients with sterile SC, and to analyze the predictors for post percutaneous nephrolithotomy (PCNL) sepsis; and to describe the type and resistance patterns of bacteria responsible for post PCNL sepsis. From a cohort of 206 consecutive patients undergoing PCNL, we identified 45 patients with a positive SC (group A) and compared them to patients with a sterile SC (group B). Association between different groups was assessed using Chi square, two-tailed Student's t test and Mann-Whitney U test, as appropriate.

Urinary retention in children.

Objective: To describe the causes and outcome of urinary retention in children and assess its prevalence by gender and age.

Methods: The medical records of all children (aged <18 years) who presented to the emergency room with acute urinary retention from 2000 to 2012 were reviewed. Patients with postoperative urinary retention, a known neurologic disorder, and neonates were excluded.

Urinary stone composition in Israel: current status and variation with age and sex--a bicenter study.

Background And Purpose: The epidemiologic data regarding stone composition in Israel are based on anachronistic methods of stone analysis. Historically, Israel was noted for an unusually high percentage of uric acid stones. The aim of the study was to describe the current stone composition distribution in Israel, using modern techniques of urinary stone analysis.

The impact of retrograde intrarenal surgery for asymptomatic renal stones in patients undergoing ureteroscopy for a symptomatic ureteral stone.

Background And Purpose: In the era of rigid ureteroscopy (URS) for ureteral stones, asymptomatic renal stones were often left in place. With the advent of flexible URS, however, the treatment of such renal stones became an attractive option. Data are scarce regarding the impact of retrograde intrarenal surgery (RIRS) performed at the time of URS for a symptomatic ureteral stone in comparison with ureteral stone removal alone.

Histology proved malpositioning of dextranomer/hyaluronic acid in submucosal ureter in patients after failed endoscopic treatment of vesicoureteral reflux.

Purpose: We histologically investigated the cause of failed endoscopic treatment of vesicoureteral reflux with dextranomer/hyaluronic acid injections in children.

Materials And Methods: A total of 192 children underwent dextranomer/hyaluronic acid injection at our institution between January 2008 and September 2010. The study population consisted of 13 children (22 ureters) with vesicoureteral reflux who underwent ureteroneocystostomy following failed endoscopic injections (1 to 2) of dextranomer/hyaluronic acid.

Patient And Methods: • A search of our institutional database yielded 4144 patients who underwent TURBT from 1996 to 2008, of whom 15 (0.36%) required open surgical intervention to repair a large bladder perforation.

Continuous epidural versus nonepidural analgesia for post-pyeloplasty pain in children.

Purpose: We compared the effectiveness of post-pyeloplasty epidural and nonepidural analgesia in children.

Material And Methods: After flank dismembered open pyeloplasty 45 children were randomly allocated to group 1-continuous epidural analgesia with a loading dose of 0.25% bupivacaine or 0.

Predictors of nocturia quality of life before and shortly after prostatectomy.

Objectives: To evaluate the predictors of nocturia-related quality of life and to assess the early effect of prostatectomy on these parameters in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction.

Methods: The study group included 56 consecutive patients scheduled for prostatectomy to treat medical treatment-refractory lower urinary tract symptoms. Nocturia severity was assessed preoperatively and 2 to 3 months after prostatectomy by the number of nocturia events, time from falling sleep to first awakening to void (hours of undisturbed sleep [HUS]), longest sleep interval between voids, and score on the nocturia quality-of-life (N-QOL) questionnaire (range 0 to 48).

Expanding use of ureteral access sheath for stones larger than access sheath's internal diameter.

The internal diameter of the ureteral access sheath limits the size of stones that can be removed during flexible ureteroscopy. We describe a technique that allows removal of larger stones, which are entrapped and removed en bloc with the access sheath. This new technique was shown to be efficient and safe.

Continuous positive airway pressure reduces nocturia in patients with obstructive sleep apnea.

Objectives: To examine whether treatment with continuous positive airway pressure (CPAP) reduces nocturia in patients with obstructive sleep apnea (OSA).

Methods: This prospective clinical study recruited patients referred to the Rambam Sleep Laboratory with suspected OSA. After polysomnography, those found to have no OSA were excluded from the study, and the remainder were treated with CPAP.

[The treatment options for localized prostate cancer].

Prostate cancer is a very common tumor in men. Today the disease is very often diagnosed early because of an elevated PSA without symptoms and the disease is localized to the prostate. Patients with prostate cancer can be divided into 3 subgroups for the carcinoma: favorable, moderate, and poorly.

Testicular torsion in the pediatric age group: diagnosis and treatment.

Purpose: To review and update several aspects of testicular torsion.

Incidence: The relative incidence of testicular torsion, torsion of testicular appendix and epididymo-orchitis is variable and depends on mode of diagnosis and patients' age. AGE: Testicular torsion can occur at any age.

Dismembered pyeloplasty in children: a review of 5 years single center experience.

Aim: Dismembered pyeloplasty is the treatment of choice for significant ureteropelvic junction obstruction in children. In the present study, we review our experience in 103 pediatric patients and present the clinical characteristics, the surgical treatment and its complications and the long term results.

Methods: We have reviewed the medical charts of 103 consecutive patients who underwent dismembered pyeloplasty in a 5-year period, from 1997 to 2002.

Percutaneous nephrolithotomy in patients who previously underwent open nephrolithotomy.

Background And Purpose: Open stone surgery nowdays is rare. However, some patients who are treated today have in the past undergone open nephrolithotomy. The aim of this study was to determine the possible impact of open nephrolithotomy on the efficacy and morbidity of subsequent percutaneous nephrolithotomy (PCNL).

Complications of circumcision in Israel: a one year multicenter survey.

Background: In Israel, virtually all children undergo circumcision in the neonatal period. Traditionally, it is commonly performed by a "Mohel" (ritual circumciser) but lately there is an increasing tendency among the educated secular population to prefer a medical procedure performed by a physician and with local anesthetic injection.

Objectives: To evaluate the outcome of this procedure and to compare the complication rate following circumcisions performed by ritual circumcisers and by physicians.

Assessment of vesicoureteral reflux in patients with self-retaining ureteral stents: implications for upper urinary tract instillation.

Purpose: Conservative treatment of upper urinary tract tumors has been popularized during the last decade. Like in bladder cancer management, localized adjuvant therapy has been advocated to reduce the risk of disease recurrence or progression. In this study we tested the feasibility of creating vesicoureteral reflux (VUR) using a Double-J stent (Medical Engineering Corp.

Deleted-in-colon-cancer protein expression in patients with adenocarcinoma of the urinary tract and a history of colorectal cancer.

Objectives: To assess whether immunostaining for deleted-in-colon-cancer (DCC) protein, a previously established prognostic marker in colon and bladder cancer, may assist in resolving the uncommon differential diagnostic dilemma of distinguishing primary from secondary urothelial adenocarcinoma.

Methods: The study group consisted of 12 patients with adenocarcinoma involving the bladder or ureter and previously resected colorectal carcinoma between 1988 and 2002. All patients were initially considered to have primary urothelial transitional cell carcinoma, and the management strategy was conducted accordingly.

Continence and quality of life assessment after artificial urinary sphincter implantation.

Background: Sphincter-related incontinence after radical prostatectomy, benign prostatectomy or due to neurogenic disease has a considerable negative impact on quality of life. Artificial urinary sphincter implantation is a mainstay therapeutic option for these patients.

Objectives: To assess patient satisfaction, subjective long-term continence and complications after AMS 800 artificial urinary sphincter implantation.
