Objective: To assess the efficacy and safety of extracorporeal shock wave lithotripsy or pneumatic ureteroscopic lithotripsy for lower ureteral stones therapy, we sought to identify and summarize randomized controlled trials that were used to treat distal ureteral stone. Methods: Eligible studies were identified from electronic databases. Database search, quality assessment, and data extraction...

The study of distal ureter function was carried out on patients with stones in the upper urinary tract, who underwent ureteroscopy and lithotripsy procedures. The parameters of ureteral peristalsis such as peristalsis amplitude, peristalsis rate, ureteral wall tone, contractile wave duration, and its direction obtained by multichannel impedance ureterography were assessed and compared from two ...

OBJECTIVE To report our experience with silent ureteral stones and expose their true influence on renal function. METHODS We analyzed 506 patients who had undergone ureterolithotripsy from January 2005 to May 2010. Silent ureteral stones were calculi found in the absence of any specific or subjective ureteral stone-related symptoms. Of the 506 patients, 27 (5.3%) met these criteria (global co...

56 percutaneous nephrostomies were evaluated in 50 patients, with a malignant underlying factor in 32 and benign conditions in 24. the clinical indication was decompression for supravesical obstruction with or without azotemia in the majority of cases. less common indications were management of ureteral fistula, ureteral stricture dilatation, and pelvic stone extraction. serious complications w...

Urolithiasis is the third most common urological disease affecting the urinary tract. However, the risk factors that may influnce the calculous kidney damage is still unclear and needs further evaluation. We retrospectively reviewed the records of 661 patients who presented to our hospital and underwent surgery for urolithiasis. All laboratory test results were obtained operatively, within a we...

BACKGROUND Alfuzosin has been widely used to treat benign prostatic hyperplasia and prostatitis, and is claimed to be a selective agent for the lower urinary tract with low incidence of adverse side-effects and hypotensive changes. Recently, several randomized controlled trials have reported using Alfuzosin as an expulsive therapy of ureteral stones. Tamsulosin, another alpha blocker, has also ...

PURPOSE To evaluate predictors of the success rate for one session of shock wave lithotripsy (SWL), focusing on the relationships between pretreatment hydronephrosis grade and one-session SWL success rates. MATERIALS AND METHODS The medical records of 1824 consecutive patients who underwent an initial session of SWL for treatment of urinary stones between 2005 and 2013 were reviewed. After ex...

This study aimed to evaluate the clinical value of a novel ureter dilatation method during ureteroscopic pneumatic lithotripsy in patients with ureteral calculi and polyps. Clinical information of 86 patients with ureter calculi and polyps who underwent ureteroscopic pneumatic lithotripsy was reviewed. A cavity-distention machine was used in 44 cases to inject normal saline for keeping clear op...

Background. In some cases, the ureteral stone is simultaneously stabilized by a stone basket when endourologic lithotripsy is performed. This stabilization can be either on purpose or by accident. By accident means that an impaction in the ureter occurs by an extraction of a stone with a basket. A stabilization on purpose means to avoid a retropulsion of the stone into the kidney during lithotr...

We report the first case of totally tubeless outpatient percutaneous nephrolithotomy (PCNL). Our patient was discharged home safely less than 4 hours following uncomplicated PCNL with no nephrostomy tube, ureteral stent, or urethral catheter. Follow-up the next day in clinic confirmed that the procedure was successful, as the patient was clinically well and stone free. To our knowledge, this is...
