BACKGROUND To evaluate the accuracy of helical computerized tomography urography (CTU) in diagnosing urinary tract disease. METHODS We collected 102 patients who underwent CTU from March 2001 to September 2002. The clinical symptoms of these patients included: flank pain or hematuria, which were clinically suggestive of urinary system disorders. All patients received CT scan with or without i...

Kidney stones are one of the oldest known and common diseases in the urinary tract system. Various human studies have suggested that diets with a higher intake of vegetables and fruits play a role in the prevention of kidney stones. In this review, we have provided an overview of these dietary plants, their main chemical constituents, and their possible mechanisms of action. Camellia sinensis (...

The aim of the present study was to summarize the management of upper urinary tract calculi in crossed fused renal ectopia (CFRE). Two patients were retrospectively studied in Xiangya Hospital (Changsha, China) and all relevant literature published in English between 1996 and 2016 was reviewed. All patients, including those reported in the literature, were characterized by age, sex, manifestati...

among 2379 patients with upper urinary tract stones who underwent eswl (extracorporeal shock wave lithotripsy) at sina hospitál using the siemens lithostar, 638 developed stone street (steinstrasse). of these, 516 (81%) passed all of the stone fragments spontaneously and no treatment was required, 90 cases (14%) had more eswl sessions to complete the treatment, and 30 (4.7%) required further in...

BACKGROUND Tamsulosin is an α-1A-specific blocker which induces selective relaxation of ureteral smooth muscle with subsequent inhibition of ureteral spasms and dilatation of the ureteral lumen and facilitates stone expelling. OBJECTIVES In this study we aimed to assess the efficacy of tamsulosin for improving the success rate of ureteroscopic lithotripsy (URS) for lower ureteral stones. PA...

Percutaneous nephrolithotomy (PCNL) has evolved to become the preferred minimally invasive approach for treating large-burden renal stones. This approach has replaced open renal surgery for stones. It has also evolved into a treatment option for treating noninvasive urothelial tumors of the upper urinary tract. Current percutaneous access techniques involve fluoroscopic or ultrasound guidance w...

Ureteric stones are a common cause of obstruction of the urinary tract, usually presenting with characteristic signs and symptoms, such as acute ureteric colic and hematuria. Occasionally, stones may present with non-specific symptoms such as low back pain and remain unidentified, leading to stone growth, chronic ureteric obstruction and complications such as hydronephrosis and renal damage. He...

BACKGROUND AND OBJECTIVES Studies of patients with benign pathologic lesions who underwent laparoscopic radical nephroureterectomy (RNU) with preoperative suspicion of upper urinary tract urothelial carcinoma are lacking. The aim of this retrospective cross-sectional study was to evaluate the incidence of benign pathologic lesions on laparoscopic RNU for upper urinary tract tumors that are pres...

Trichobezoar is a rare condition whereby a hairball is found in the human stomach or gastrointestinal tract, most frequently in young women, mainly in association with a psychiatric disorder. Trichobezoar cases have also been reported in the bladder and represent a rare complication of foreign bodies, called "hair nidus or hair ball," in patients with chronic catheter. Approximately 10% to 15% ...

Urethritis associated with urinary calculi is of rare occurrence. Harkness (1950) described cases of urethritis secondary to stones in the urethra, bladder, prostate and Cowper's glands. He also gave the history of a patient who developed acute non-specific urethritis, which was cured without active treatment when a renal stone was passed spontaneously after an attackofureteric colic. Since the...
