[Comparative study of overactive bladder prevalence in patients younger than 50 years with and without hyperprolactinemia]. / Estudio comparativo de la prevalencia de vejiga hiperactiva en pacientes menores de 50 años con y sin hiperprolactinemia.

OBJECTIVE: To determine if the hyperprolactinemia is associated with idiopathic overactive bladder. PATIENTS AND METHODS: We performed a transversal and analytic two groups study. We included all the patients whom plasma levels of prolactin were measured in the National Institute of Perinatology from March 1st to May 31, 2005 and fulfilled the selection criteria. To all these patients we applied a questionnaire of eight questions for the overactive bladder diagnostic. We used chi square statistical technique to establish if hyperprolactinemia is associated with the overactive bladder. RESULTS: One hundred sixty years patients were studied, establishing a relative prevalence of 2.82 (IC 95%: 1.45-3.17), determining association between the variables. CONCLUSIONS: hyperprolactinemia is associated with overactive bladder.

[Low urinary tract infection and cystoscopic findings in Urogynecology Service in the Instituto Nacional de Perinatología]. / Infección de vías urinarias bajas y hallazgos cistoscópicos en el Servicio de Uroginecología del Instituto Nacional de Perinatología.

INTRODUCTION: The pathogenesis of urinary tract infection and related to the host and pathogens. There are three associated factors: incontinence, cystocele and residual urine. OBJECTIVES: To know the prevalence of urinary tract infections and uropathogens in urogyneacologic patients of the Instituto Nacional de Perinatología describe the cystoscopic findings in patients with positive urocultures and antibiogram. METHODS: This is a retrospective study involving urogyneacologic patients with positive urine cultures from 1998 to 2001. Positive culture was a growth of only one microorganism more than 100,000 colonies. The antibiogram and patients files were reviewed in order to know: Symptoms, indications, diagnostic and cystoscopic findings; their distribution and differences were analyzed. RESULTS: From 3,433 urine cultures, 540 were positive (16% prevalence). Uropathogens distribution was: E. coli 70%, Klebsiella pneumoniae 6.3%, Pseudomonas aeruginosa 4.3%. The antibiogram showed resistance to beta-lactamics and third generation cephalosporin (96.59% and 85.17%). The most frequent indications were: incontinence, irritative symptoms, urethral hypermovility and pelvic organ prolapse. Urethrothrigonitis was the most frequent cystoscopic finding. Mixed urinary incontinence and urethral hypermotility were the only findings to have a important difference. CONCLUSIONS: There is a change in the uropathogens prevalence and in their antibiotic resistance. This must be considering in the treatment of urogyneacologic patients with urinary tract infections. To ensure the best outcome we must ask for a urine culture with antibiogram. The additional use of anti-inflammatory agents is convenient in the presence of urethrothrigonitis in urogyneacologic patients with urinary tract infections.
