Urinary retention concomitant with methamphetamine use: a case report

Urinary retention is a condition in which impaired emptying of the bladder results in postvoid residual urine. It can be acute or chronic urinary retention. There have been only scattered case studies that have described urinary retention resulting from methamphetamine use. This case report is aimed at raising awareness about methamphetamine abuse as an important factor in the aetiological considerations when evaluating cases of urinary retention among healthy younger age groups.

We report a patient who had acute urinary retention after brief amphetamine use. A 26-year-old Nigerian man presented at the emergency room on account of an inability to pass urine and lower abdominal pain. Before this incident, the patient reported a recent ingestion of amphetamine to achieve weight reduction and a fit body. A week after use, he started to experience difficulty passing out urine hence necessitating a visit to the emergency department. After a brief assessment, physical examination revealed a man in painful distress with mild suprapubic fullness. He had a successful passage of a urethral catheter for continuous bladder drainage with dramatic improvement in his symptoms. He was subsequently discontinued on methamphetamine use and referred to a urologist for further evaluation.

Most cases of urinary retention are diagnosed clinically and are rarely missed. But because urinary retention is associated with a wide range of aetiological factors, clinicians need to be aware of the effects of certain drugs in the aetiology of urinary retention. In the management of a case of urinary retention in the younger age group, clinicians should enquire about a history of drug use, the drug of particular interest being methamphetamine, and also employ the use of urodynamic studies in the evaluation of such cases.
