We describe a case of a 3-year-old boy with Down syndrome who developed a bladder rupture as a consequence of an undiagnosed posterior urethral valve (PUV). He had a history of urinary tract infections and constipation and was acutely admitted in poor condition and underwent laparotomy that revealed peritoneal sepsis secondary to bladder perforation. Bladder was drained using a suprapubic catheter and the condition of the boy gradually improved. Once stable, a cystourethroscopy confirmed the presence of PUV. Video-urodynamic studies performed at the check cystoscopy showed the bladder to be of reduced compliance (end fill pressure at 100 mL fill 30 cmH2O) with raised voiding pressures (76–100 cmH2O) and significant incomplete bladder emptying. Currently, the patient is doing very well, serum creatinine has normalised, he is infection-free and thriving; his bladder is managed with a vesicostomy.
