double-j (dj) stents are the main tools used in urological practice for prevention and treatment of obstruction. stenting is also mandatory after complicated ureteroscopy or tul (transureteral lithotripsy). known complications are upper migration of dj stents into the kidney and lower migration to the bladder. in a man with an impacted right lower ureteral stone, a dj stent was placed because t...

INTRODUCTION The accurate diagnosis of submucosal ureteral stones in order to choose a proper and less complicative method of treatment is of significant importance. The use of KUB to detect submucosal ureteral stones has been studied in this research. MATERIALS AND METHODS This prospective study has been carried out on 33 patients (23 males and 10 females) with lower ureteral stone (17 cases...

PURPOSE To evaluate ureteral stenting as a negative predictive factor influencing ureteral stone clearance and to estimate the probability of one-session success in shock wave lithotripsy (SWL) patients with a ureteral stone. MATERIALS AND METHODS We retrospectively reviewed the medical records of 1,651 patients who underwent their first SWL. Among these patients, 680 had a ureteral stone mea...

INTRODUCTION We intended to evaluate the feasibility and effectiveness of the simultaneous rigid and flexible ureteroscopic treatment of symptomatic ureteral and ipsilateral small simultaneous calyceal stones. Outcomes of combined therapy were compared with monotherapy alone. MATERIAL AND METHODS In this retrospective study, group 1 consisted of 45 patients with middle or lower ureteral and i...

PURPOSE For treating proximal ureteral calculi, treatment decision has been known still difficult to choose ureteroscopic lithotripsy (URS) or shockwave lithotripsy. The aims of our study are to identify the possible predictors for necessity of URS and to propose the Gachon University Ureteral Narrowing scoring system (GUUN score) as a helpful predictor. MATERIALS AND METHODS We evaluated 83 ...

PURPOSE The aim of this study was to evaluate the effectiveness of simultaneous flexible ureteroscopic removal of stones (URS) for ureteral and ipsilateral renal stones and to analyze the predictive factors for renal stone-free status. MATERIALS AND METHODS We retrospectively reviewed the records of patients who underwent simultaneous flexible URS of ureteral and ipsilateral renal stones from...

A twenty-eight-year-old female with a history of suprapubic pain and recurrent urinary tract infections presents for urology referral with a kidney, ureter, and bladder radiograph showing a 4.4 cm bladder calculus and 6.5 cm distal left ureteral stone. She underwent effective cystolitholapaxy of the bladder stone. Endourologic attempt (left ureteroscopy) was unsuccessful because of ureteral sto...

PURPOSE We examined patient satisfaction with treatment outcomes after shock wave lithotripsy (SWL) and ureteroscopic removal of stone (URS) for proximal ureteral stones. MATERIALS AND METHODS We evaluated 224 consecutive patients who underwent SWL (n=156) or URS (n=68) for a single radiopaque proximal ureteral stone. Stone-free rates, defined as no visible fragment on a plain X-ray; complica...
