Crossed renal ectopia is a rare congenital anomaly in which both kidneys are situated on one side and fused together in 85%-90% of cases. The management of urinary calculi in patients with crossed renal ectopia continues to pose challenges to urologists because the aberrant anatomy may make access and clearance of the calculi more difficult to accomplish. Here, we report a case of inferior cros...

Received November 2009 Accepted July 2010 INTRODUCTION Since 1980, the extracorporeal shockwave lithotripsy (SWL) has become the gold standard option for treatment of renal and ureteral calculi. But SWL is not without complication and has its own contraindications. Of absolute contraindication for SWL is bleeding tendency. Here, we report a case with bleeding diathesis who underwent SWL without...

A 33-year-old male with an ileal conduit was referred to our department for the treatment of left renal calculi. After inserting a ureteral access sheath, a ureteroscopy-assisted retrograde nephrostomy was made. Percutaneous nephrolithotomy was successfully achieved using this nephrostomy.

Kedney matrix stones are a rare form of calculi. Flank pain and urinary tract infections (UTI) are the most common presentations of matrix calculi. The diagnosis is usually made at surgery, but some preoperative radiographic findings might be suggestive. Open surgery was the method of choice for treatment. However, combination of ureterorenoscopy and percutaneous nephrolithotomy (PCNL) was foun...

This article aims to explore the characteristics of computed tomography (CT) images of ovarian vein syndrome (OVS). The approval of the research ethics committee and the written informed consent of the patients were obtained. The CT images of 11 patients who had been diagnosed with OVS were retrospectively analyzed. All patients were examined with CT urogram, both plain CT scans and enhanced CT...

Ureteral obstruction can occur due to various pathologies. Ureteral calculus is one of the commonest causes. Extra luminal and less commonly intra luminal Ureteral obstruction can occur due to malignancy. Unrecognised Ischemic injuries during gynaecological surgery can cause ureteric stricture and obstruction at a later date. Traumatic injuries have also been documented as an important cause of...

A 67-year-old male renal transplant patient presented with a right inguinal bulging mass, and was diagnosed with a right indirect inguinal hernia. The day following inguinal herniorrhaphy, serum creatinine became elevated. The patient was oliguric and had abdominal pain on the first day after inguinal herniorrhaphy with a mesh. We diagnosed him with acute renal failure and subsequently performe...

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...

PURPOSE To determine the efficacy and safety of emergency ureteroscopy (URS) and holmium:yttrium-aluminum-garnet (Ho:YAG) laser lithotripsy for ureteral calculi that are associated with acute renal failure (ARF). PATIENTS AND METHODS We retrospectively evaluated a cohort of 49 patients who underwent URS from November 2005 to November 2008 for ARF that was caused by calculi obstruction of the ...
