BACKGROUND Diphallia is a highly uncommon congenital urogenital abnormality and a few connected reports have been published.However,no case of intraabdominal heterotopic diphallus has been documented to date.In the present study,we present a rare case of intraperitoneal ectopic bipenis.CASE SUMMARY A 49-year-old man was hospitalized with the chief complaint of hydronephrosis of both kidneys,which was discovered three days earlier through regular physical examination performed using urological ultrasound without significant lumbar or abdominal pain or bladder irritation.Physical examination showed normal external penile development,bilateral testes located on the left side of the scrotum,and a fused epididymis.Urological plain and enhanced computed tomography suggested bilateral hydronephrosis,bilateral ureters opened to the left side of the bladder wall;an intrapelvic soft tissue shadow on the left side of the bladder was considered a germline malformation called bipenis(hidden penis in the abdominal cavity).Based on the urological plain and enhanced computed tomography results,a 49-year-old man was diagnosed with bipenis(one hidden in the abdominal cavity).Ectopic penile compression produced bilateral ureteral dilatation and hydronephrosis.The ectopic penis was amputated and partially removed during surgery,and bilateral ureteral replantation was successfully performed.At a 2-mo follow-up,the patient was very satisfied with the operation,there was no significant hydronephrosis in both kidneys,and urination and erectile function were normal.CONCLUSION To our knowledge,this is the first report of diphallia with an intraperitoneal ectopic penis.Computed tomography or magnetic resonance imaging can be used to assess the associated internal anomalies before surgery.Postoperative pathological findings are the gold standard for the diagnosis.
