Balanoposthitis associated with the presence of subpreputial "smegma stones".

Abstract

coitus. Examination revealed an inflamed, only partially retractable prepuce with a purulent subpreputial discharge. Adequate urethral swabs were unobtainable; however, a subpreputial swab for bacterial culture was performed and subsequently grew Proteus spp, Pseudomonas spp, coliform bacilli, anaerobes, and non-candida yeasts.

He was prescribed fluconazole 150 mg immediately and metronidazole 200 mg three times daily for 1 week and advised to irrigate gently with normal saline under the prepuce. On follow up at 1 week there had been a marked improvement. The prepuce was now fully retractable, albeit with some difficulty.
