Unilateral Lower Limb Oedema: An Unusual Presentation of High-Pressure Chronic Retention.

High-pressure chronic retention (HPCR) is a well-recognized common urological emergency which requires prompt treatment. It usually presents with nocturnal enuresis, a tense and palpable bladder, and symptoms of uraemia from renal failure George et al 1983.1 There have been isolated cases in the literature of HPCR presenting with symptoms of venous occlusion secondary to extrinsic bladder compression2,3 but it remains a rare presenting complaint. We discuss the case of a 56-year-old man who presented primarily with right lower limb swelling which was later revealed to be due to HPCR.
