OBJECTIVES To evaluate factors contributing to bleeding after percutaneous nephrolithotomy (PCNL) and ways of managing this complication, as bleeding is a serious sequela that requires prompt management. PATIENTS AND METHODS The demographic and procedural data of 200 patients, who underwent unilateral PCNL during a 20-month period, were prospectively collected. Preoperative, operative, and po...

UNLABELLED We investigated the value of supranormal function and renogram patterns on (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) scintigraphy in relation to the extent of hydronephrosis for predicting ureteropelvic junction (UPJ) obstruction in the newborn. METHODS We studied 48 patients with prenatally diagnosed unilateral hydronephrosis that was confirmed on postnatal ultrasonography. ...

In a previous paper (Keith and Pulford) we described a method for producing experimental hydronephrosis, which permitted the study of renal function in this condition for periods varying from weeks to months. The method used was the partial obstruction of both ureters near the ureteropelvic juncture. After a thorough functional study of hydronephrosis thus produced, further experiments were car...

The incidence of endometriosis cases involving the urinary system has recently increased, and the bladder is a specific zone where endometriosis is most commonly seen in the urinary system. In the case presented here, a patient presented to the emergency department with the complaint of side pain and was examined and diagnosed with severe hydronephrosis and bladder endometriosis was determined ...

Corticosteroids were successfully used to treat a 66-year-old man with retroperitoneal fibrosis (RPF) and previously diagnosed membranous nephropathy. Proteinuria was noted at the age of 51 years, and membranous nephropathy was diagnosed by renal biopsy. Ten years later, he presented with right hydronephrosis and renal dysfunction, and was diagnosed as having RPF based on the typical diagnostic...

1. In acute experimental hydronephrosis chloride retention occurs as well as retention of water, urea, and phenolsulfonephthalein. 2. If both water and chlorides are retained there may be no appreciable rise in the plasma chloride content. 3. When chlorides are retained, but not water, the chloride content of the plasma rises strikingly. 4. After the removal of the ureteral obstruction in acute...
