Anterior urethral valves: an uncommon cause of obstructive uropathy in children.

Purpose: Anterior urethral valves (AUV) are rare entities generally described in case reports. They are an uncommon cause of lower urinary tract obstruction in children and can be difficult to diagnose. In the present study, we present our experience in four children with AUV along with a literature review.

Recovery of abnormal ejaculation by intermittent tamsulosin treatment.

Purpose: We assessed the impact of intermittent tamsulosin treatment on abnormal ejaculation.

Materials And Methods: This prospective study was performed between January 2001 and December 2004. It included 405 patients who were at least 50 years old with lower urinary tract symptoms.

Renal papillae metastasis of sigmoid colon adenocarcinoma.

Colonic carcinoma metastatic to the kidney is very rare. The usual anatomical localization for secondary renal neoplasms is the renal cortex. We report a case of sigmoid colon carcinoma with unilateral kidney metastasis localized only in the renal papillae without obvious metastatic disease.

The effects of subinguinal varicocelectomy on Kruger morphology and semen parameters.

Purpose: We studied the effect of varicocele ligation on Kruger strict morphology criteria and semen parameters in patients with infertility.

Materials And Methods: A total of 90 patients diagnosed with varicoceles and a normal morphological sperm ratio of less than 14% were evaluated before and 6 months after varicocelectomy. Preoperatively and postoperatively sperm density, motility and morphology using Kruger strict criteria were analyzed.

Diagnostic approach to prostate cancer using total prostate specific antigen-based parameters together.

This prospective study investigated the value of serum total prostate specific antigen (tPSA)-based parameters in the diagnosis of prostate cancer (PCa). Serum tPSA, free to tPSA ratio (f/tPSA), PSA density (PSAD), and PSA transition zone (PSAT) were evaluated in 110 patients with histologically confirmed benign prostate hyperplasia (BPH) and 98 patients with PCa. Once the serum tPSA was elevated (greater than 4 ng/ml) or digital rectal examination (DRE) was suspicious, transrectal ultrasound-guided biopsies were recommended.
