BACKGROUND Laser lithotripsy is an established endourological modality. Ho:YAG laser have broadened the indications for ureteroscopic stone managements to include larger stone sizes throughout the whole upper urinary tract. Aim of current work is to assess efficacy and safety of Ho:YAG laser lithotripsy during retrograde ureteroscopic management of ureteral calculi in different locations. MET...

Background: Urinary calculi have serious implications in urology. Lower ureteral stones can cause obstructive uropathy and subsequent deterioration of renal function. Because the patient’s symptoms stone size do not predict loss function because there is no clear time threshold for irreversible damage, treatment should be strongly considered any patient with stones. In this study we are compari...

INTRODUCTION We compared the efficacy of extracorporeal shock wave lithotripsy (SWL) with ureteroscopy followed by transureteral lithotripsy (TUL) for the treatment of impacted distal ureteral calculi. MATERIALS AND METHODS A total of 96 patients with solitary impacted distal ureteral calculi were assigned into 2 groups of treatment with SWL (42 patients) and TUL (54 patients) with a 6.9-F se...

PURPOSE This retrospective study evaluated the unenhanced multi-detector computed tomography (MDCT) findings of urinary system calculi and the secondary signs associated with ureteral stones in children. MATERIALS AND METHODS The study included 87 children (54 boys, 32 girls) with a mean age of 89 months (range: 5 months to 16 years) who were referred to us from various departments and were e...

Urolithiasis can result as a complication of urinary diversión, favored by urinary stasis, intestinal mucus, urinary tract bacteriuria, the metabolic derangements and the presence of foreign bodies. We present a 52- year-old male who underwent radical cystectomy with construction of a Bricker uretero-ileostomy. 5 years later he was found with a forgotten ureteral stent, a 6 cm calculi occupying...

We reviewed the outcome of 300 cases without urinary tract infections to determine the relationship between leucocytosis and severe pain due to ureteral calculi. Leucocytosis above 9,000 cells per cmm was seen in 87.7% of the cases. Many patients (61%) had a leucocyte count between 9,000 and 12,000, but none had that exceeding 22,000. This leucocytosis can be attributed to a transient distribut...

Objective: 1) Prospective comparison of unenhanced spiral computed tomography (NCCT) with Intravenous Urography (IVU) and Combination of CT scout with Ultrasound (CT+US) in the Evaluation of acute renal colic. 2) To formulate a model for predicting the probability of the presence of ureterolithiasis while simultaneously assessing the effects of Body Mass Index (BMI), Size of calculi, Hydronephr...

PURPOSE Despite the routine use of helical CT in diagnosis of renal colic, there are recent concerns regarding the radiation exposure, overuse and costs. We attempted in this retrospective study to evaluate the accuracy of ultrasound (gray-scale and color Doppler with twinkling), KUB and urinalysis in diagnosis of renal colic due to ureteral calculi presented in Emergency Room. MATERIALS AND ...

INTRODUCTION The aim of this study was to evaluate the treatment of upper ureteral calculi with extracorporeal shock wave lithotripsy (SWL) in the supine and prone positions. MATERIALS AND METHODS A total of 68 patients with upper ureteral calculi underwent SWL. In 35 patients, the procedure was performed in the supine position (group 1), while in the 33 remainders, it was performed in the pr...

OBJECTIVES The ultrasonographic diagnosis of renal lithiasis colic is suggested by the existence of hydronephrosis, but the certainty is given by the direct visualization of the ureteral calculus. The aim of this study is to assess the performance of ultrasound in identifying ureteral calculi compared to other imaging methods (abdominal X-ray, urography and computed tomography).
