Cystoscopic removal of leeches in the lower urinary tract: our experience

The purpose of this study is to describe the experience of managing leech infestation in lower urinary tract from a tropical country.

Medical records (January 2002 to December 2010) of children with history of leech infestation in the urinary system, admitted in the Department of Pediatric Surgery, Chittagong Medical College & Hospital, Chittagong, Bangladesh were reviewed. All patients underwent saline irrigation through urethral catheter. When saline irrigation failed, cystoscopic examination was done with removal of leeches by flexible graspers. Follow-up was done 2 weeks later.

The study included 117 patients. Age ranged from 4 to 12 years. Male and female ratio was 3.7:1. All patients had per urethral bleeding. 51 (43.6%) patients had suprapubic pain. All children underwent saline irrigation through urethral catheter. Spontaneous expulsion occurred after saline irrigation in 57 (48.7%) patients. The expelled leeches were alive in 11 cases; dead in 46 patients. Cystoscopic removal of leeches was done in 60 patients (51.3%). In the cystoscopic group, 54 of the removed leeches were dead and 6 were alive.

Cystoscopic removal can be a useful technique for the removal of leeches from the urinary tract when saline irrigation fails.
