Patterns of Benign Prostatic Hyperplasia Associated Urinary Retention: Indwelling Urinary Catheter Use and Clinical Sequelae.

INTRODUCTION

Current clinical practice guidelines aim to decrease the use of unnecessary indwelling urinary catheters to prevent catheter associated urinary tract infections. Patients with benign prostatic hyperplasia often experience increased post-void residual urine volume and subsequent bladder catheterization to prevent complications such as urinary tract infections or hydronephrosis. However, the management of urinary retention in patients with benign prostatic hyperplasia varies and clinical guidelines are lacking. In this study we gather information on post-void residual urine volume, the use of catheters and associated complications in a sample of older veterans with benign prostatic hyperplasia.

METHODS

A retrospective chart review was performed using 660 patients screened for documented post-void residual urine volume greater than 100 cc, age greater than 65 years and the absence of cancer. A final chart review of 136 male veterans was performed for this analysis.

RESULTS

A total of 59 (43.4%) indwelling urinary catheters were placed. Catheters were placed in subjects with modest post-void residual urine volumes in the 100 to 150 cc range and in those with a post-void residual urine volume greater than 500 cc. Overall complication rates were low. Among those patients who had a catheter placed 51% reported hematuria, 36% reported pain and only 1 had documented urosepsis. Hydronephrosis occurred in 4 cases, each with a post-void residual urine volume of 301 to 400 cc, and 3 of these individuals had an indwelling urinary catheter placed. In those patients emergency room visits and hospitalizations were more frequently associated with placement of an indwelling urinary catheter.

CONCLUSIONS

Larger studies are needed for the development of clinical guidelines on the treatment of patients with benign prostatic hyperplasia and urinary retention.
