We herein report a rare case of nontraumatic urethral rupture. The patient presented with oliguria, perineal pain and anorexia, and a 3 cm fistula was located in the perineum. Computed tomography revealed a retroperitoneal abscess invading the urethra, and a retrograde urethrogram revealed the rupture of the membranous urethra.

Methods: A total of 47 patients who received radical nephroureterectomy and underwent both preoperative dynamic computed tomography and renography were the model-development cohort; and 109 patients who underwent dynamic computed tomography alone were the validation cohort. Postoperative renal function of the unremoved kidney was estimated using the following formulas: preoperative estimated glomerular filtration rate × the percentage of total renal cortex radiodensity for the intact kidney in Hounsfield units obtained from corticomedullary phase images in the computed tomography-based model, or the percentage of the total glomerular filtration rate measured by renography in the nuclear model.
Background/aim: We investigated the prognostic role of the albumin/globulin ratio (AGR) in patients with upper tract urothelial carcinoma (UTUC) undergoing radical nephroureterectomy (RNU).
Patients And Methods: AGR was calculated as follows: AGR=serum albumin/(serum total protein-serum albumin). Associations of preoperative AGR with disease-free (DFS) and overall (OS) survival were assessed in 105 patients with UTUC undergoing RNU.
Purpose: The Third International Consensus Definitions for Sepsis and Septic Shock Task Force proposed a new definition of sepsis based on the SOFA (Sequential [Sepsis-related] Organ Failure Assessment) score and introduced a novel scoring system, quickSOFA, to screen patients at high risk for sepsis. However, the clinical usefulness of these systems is unclear. Therefore, we investigated predictive performance for mortality in patients with acute pyelonephritis associated with upper urinary tract calculi.

Patients And Methods: Preoperative bacteriuria and pyuria were defined as urine containing ≥5 bacteria/high-power field (HPF) and >5 white blood cells/HPF, respectively. Their associations with IVR were evaluated in 97 patients with UTUC undergoing RNU.
Aim: To assess the general applicability of TNM-C scoring, which consists of TNM classification and preoperative C-reactive protein concentration, the predictive ability of the TNM-C score was externally validated for patients with clear cell renal cell carcinoma (ccRCC) at three community hospitals.
Patients And Methods: Seven hundred patients underwent radical or partial nephrectomy after being diagnosed with RCC. Out of the 700 patients, 518 with clear cell carcinoma served as the current study cohort.
Objective: To investigate the interactions between inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in response to ischaemia-reperfusion (I/R) of rabbit bladder.
Materials And Methods: Rabbit bladders were exposed to 2 h of ischaemia by bilaterally clamping the major arteries entering the bladder and then a subsequent 36 h of reperfusion (I/R) with or without intraperitoneal administration of a selective iNOS inhibitor n-(3-(amynomethyl)benzyl)acetamidine (1400W) or a selective COX-2 inhibitor NS-398 given 1 h before killing. The bladder tissues were processed for isometric tension experiments, enzymatic NOS activitiy, tissue contents of nitrite/nitrate (NO(X) ), cyclic guanosine monophosphate (cGMP) and COX activity determined by prostaglandin E(2) (PGE(2) ) production.
Purpose: Little is known about L-arginine catabolism following ischemia in the bladder. We examined the changes in nitric oxide synthase, arginase and ornithine decarboxylase activity, polyamine biosynthesis and the ability to produce nitric oxide following ischemia of the rabbit bladder.
Materials And Methods: Bladder ischemia was created by ligation of a unilateral bladder artery.
A case of adrenal myelolipoma is presented. A 39-year-old woman was admitted to our hospital for further examination of a right adrenal mass, which was found by examination for nausea, vomiting and upper abdominal pain. Imaging analyses by computed tomography and magnetic resonance imaging revealed a round fatty mass.

Recently, criteria have been developed for urologists to assess benign prostatic hyperplasia using the International Prostate Symptom Score (I-PSS), QoL index, urination function (maximal flow rates and residual urine volume) and prostate volume. It is suggested that patients with moderate to severe urination problems as measured by these criteria need to be treated but those with mild problems have no need for treatment.

Recently, criteria have been developed for urologists to assess the efficacy of benign prostatic hyperplasia treatment using the International Prostate Symptom Score (I-PSS), QoL index and maximal flow rates. We examined whether these criteria can be applied to the general urination problems of the elderly men and women, with 85 male and 16 female subjects aged 50 and over.
