Re-exploration of the acute scrotum

OBJECTIVE: To investigate children and adolescents who had scrotal exploration more than once. PATIENTS AND METHODS: Between 1994 and 2004, 64 of 840 (7.6%) boys had more than one scrotal exploration at our institution. The age, laterality of the explorations, the interval between and findings at operation, whether the testes were managed by orchidopexy and how, and the complications, were reviewed from the medical records and the operating reports of the patients. All the boys were followed at the outpatient clinic 2-4 weeks after surgery. RESULTS: The median (range) age of the patients was 11.5 (2-15) years; 61 had two scrotal explorations and three were explored three times. Of the patients, 32 presented with right testicular pain, 31 had left pain, and one had bilateral testicular pain. In the second exploration, 56 of 64 had the contralateral testis explored, five had an ipsilateral exploration and three had bilateral exploration. Forty-eight of the 64 boys (70%) had torsion of the contralateral appendix testis at the second exploration, and 5.3% (45/840) of the total number of children operated for acute scrotum had metachronous torsion of the appendix testis. The median interval between the first and second exploration was 8 months (1 day to 10.5 years). Two boys had three scrotal explorations, and three of 64 (4.7%) boys developed complications that required re-exploration. CONCLUSIONS: Most indications for recurrent scrotal exploration in this study are because of a twisted contralateral appendix testis, but the risk of developing this pathology is similar to the complication rate of repeat scrotal exploration. These data support our policy that the contralateral testis should not be routinely explored nor its appendix removed unless there is ipsilateral testicular torsion.
