Urothelial cancers encompass carcinomas of the bladder, ureters, and renal pelvis; these cancers occur at a ratio of 50:3:1, respectively. Cancer of the urothelium is a multifocal process. Patients with cancer of the upper urinary tract have a 30% to 50% chance of developing cancer of the bladder at some time in their lives. On the other hand, patients with bladder cancer have a 2% to 3% chance...

INTRODUCTION Pseudo-Meigs' syndrome is associated with tumors different from the benign ovary tumor, but it has never been described in association to transitional cell carcinoma. CASE REPORT A female 73 year-old patient presenting pleural effusion nonmetastatic associated with renal pelvis transitional cell carcinoma that resolved and did not recur after radical nephroureterectomy. COMMENT...

TSUCHIDA, S., MORITA, T. and KONDO, S. A New in Vivo Method of Recording of the Electrical Activities of the Renal Pelvis. Tohoku J. exp. Med., 1982, 136 (2), 233-234 A new method is described which enables in vivo recording of electromyogram from the pelvicalyceal border (PC border) of the canine renal pelvis. At the PC border slow rising-potentials with constant intervals are recorded through...

Objective: Since the introduction of percutaneous nephrolithotomy (PCNL), many changes have been added regarding the entrance to pyelocalyceal system such as insertion of the needle pointed to an opaque stone as a guided landmark. We aim at comparing the outcomes of managing renal calculi with and without retrograde pyelography. Materials and Methods: In a randomized clinical trial, 55 cases wi...

INTRODUCTION The aim of this study was to evaluate changes in expression of soluble biomarkers tumor factor growth-β1 (TGF-β1), CCL5/RANTES, and sFas/Apo-1 in the urine of patients undergoing ureteropyeloplasty for ureteropelvic junction (UPJ) obstruction. These factors are connected with different processes ongoing in the obstructive uropathy. If their urine concentrations correlate with AP di...

CONTEXT Clinical surveys have revealed that incidental detection of renal cell carcinoma is rising because of increased use of imaging procedures. OBJECTIVE To examine incidence, mortality, and survival trends of renal cell and renal pelvis cancers by age, sex, race, and tumor stage at diagnosis. DESIGN Calculation of age-adjusted incidence and mortality rates, along with 5-year relative su...

BACKGROUND/AIM Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis. METHODS Twenty-four infants (19 boys and five girls) present...
