[Flowmetry analysis in patients undergoing transurethral resection of the prostate for BPH]. / Análisis flujométrico en pacientes sometidos a RTU de próstata por HBP.

Transurethral resection (TUR) is the most frequent surgical treatment for symptomatic benign prostate hyperplasia (BPH). Prostate size is a significant factor for choosing TUR versus prostate adenomectomy. Analysis of flowmetry results obtained with TUR in 203 patients, based on weight of resected prostate tissue. Flowmetry was performed prior to TUR and prostate size was estimated with transabdominal ultrasound. Prostate tissue was weighed after TUR and a new flowmetry was performed 6 months after treatment. Mean weight of resected tissue was 31.34 g. When all flowmetry parameters analyzed pre-and post TURs were compare, there were significant differences (p < 0.001). Increased maximum flow (Qmax) and increased mean flow (Qmed) occurred in 91.7% and 96.31% patients, respectively. Mean increase of post-surgical Qmax was significantly higher (p > 0.01) in patients with Qmax prior to surgery lower than 8 ml/s. No significant correlation was demonstrated between prostate volume measured by ultrasound or resected prostate tissue and increased post-surgical Qmax. TUR improves flowmetry parameters, mainly in patients with pre-surgical Qmax lower than 8 mL/s. Extensive prostate resection does not appear to improve the flowmetry results obtained with a sufficient functional TUR.

[Primary mucinous adenocarcinoma of the prostate]. / Adenocarcinoma mucinoso prostático primario.

Contribution of a new case of prostatic mucinous adenocarcinoma of primary origin. Diagnosis was established by histochemical techniques alcian blue, PAS and alcian-PAS) processing the fragments from the prostate transurethral resection (PTUR). Neither the existence of extraprostatic tumoration, local infiltration, or metastasis was recognized. No correlation between preoperative prostatic acid phosphatase (PAP) (50) and prostatic specific antigen (PSA) values (3ng/m) was evidenced. After radical prostatectomy both markers remain undetected one year after surgery.

[Foreign bodies in the bladder and urethra]. / Cuerpos extraños en vejiga y uretra.

Many cases have been published in the urological literature of foreign bodies apparent in the bladder and urethra. Based on the five cases we are now presenting, we review this chapter of urology. We discuss the clinico-pathological aspects of this pathology and provide diagnostic and therapeutical guidance. We recall the role urologists have to play in preventing such events in the course of their diagnostic and therapeutic activity.
