PURPOSE We retrospectively investigated the factors that affect the success of rigid ureteroscopy in the pediatric population for the management of pediatric ureteral stones. PATIENTS AND METHODS We present a retrospective review of 61 consecutive pediatric patients who underwent 66 rigid ureteroscopy procedures for ureteral stone management. The effects of sex, age, stone diameter, stone loc...

PURPOSE The purpose of this study was to evaluate the effectiveness of combined ureteroscopic holmium YAG lithotripsy for renal calculi associated with ipsilateral ureteral stones. MATERIALS AND METHODS Between August 2002 and March 2007, retrograde flexible ureteroscopic stone treatment was attempted in 351 cases. Indication for treatment was concurrent symptomatic ureteral stones in 63 pati...

PURPOSE Typically in Korea, for a standard dose (0.4 mg) of tamsulosin, two low doses (0.2 mg) are administered. The aim of this study was to evaluate and compare the efficacy of tamsulosin (0.2 mg and 0.4 mg) and alfuzosin (10 mg) in the treatment of lower ureteral stones. MATERIALS AND METHODS A total of 141 patients presenting with a single 4- to 10-mm sized lower ureteral stone were rando...

We report a case of ureteral migration of a surgical clip after partial nephrectomy in which the clip was misdiagnosed as a ureteral stone. A 37-year-old woman had undergone laparoscopic partial nephrectomy of right renal cell carcinoma at another hospital 2 years previously. Postoperatively, she had gradually acquired lower urinary tract symptoms. Then, she complained of sudden right flank pai...

A 28-year old man presented with left flank pain and dysuria. Plain abdominal film and computed tomography showed a left giant ureteral stone measuring 11.5 cm causing ureteral obstruction and other stones 2.5 cm in size in the lower pole of ipsilateral kidney and 7 mm in size in distal part of right ureter. A left ureterolithotomy was performed and then a double J stent was inserted into the u...

Bilateral ureteral duplication is a very rare anomaly, a result of two separate ureteric buds arising from a mesonephric duct. Most of the patients are asymptomatic and diagnosed incidentally. Recurrent urinary tract infections, incontinence, haematuria, stone formation and flank pain are common clinical symptoms. Intravenous urography, computed tomography urography, and magnetic resonance imag...

INTRODUCTION We analyze our recent results and discuss the advantages and disadvantages of bilateral single-session ureterorenoscopy (URS) for bilateral ureteral stones. PATIENTS AND METHODS 55 patients underwent URS with pneumatic lithotripsy (PL) for bilateral stones. 61 (55.5%), 28 (25.4%) and 21 (19.1%) stones were located in the lower, middle and upper ureter, respectively. RESULTS Of ...

OBJECTIVE To derive and validate an objective clinical prediction rule for the presence of uncomplicated ureteral stones in patients eligible for computed tomography (CT). We hypothesized that patients with a high probability of ureteral stones would have a low probability of acutely important alternative findings. DESIGN Retrospective observational derivation cohort; prospective observationa...

PURPOSE To determine the predictive value of certain radiological parameters for an objective asssessment of the presence of ureteral stone impaction. MATERIALS AND METHODS Seventy-nine patients with a single proximal ureteral stones were retrieved from the departmental database. Both clinical and particularly radiological data of all cases were well evaluated on this aspect. In addition to t...

conclusions: administration of α-1a-specific blocker reduced analgesic dosage and colic episodes and rate of adverse effects after ureteroscopic lithotripsy of lower ureteral stones and decreased gravel expulsion time after ursl. results: the results showed that tamsulosin treatment group had low expulsion time (p = 0.011), low urinary tract symptoms, least analgesic needs and low adverse effec...
