Diagnostic laparoscopy and management of the impalpable testis – a review of 10 years' practice at a non-paediatric specialist centre

Abstract 

Background

Laparoscopy is used for the diagnosis and treatment of impalpable testes. We reviewed practice and outcomes in our unit over the last 10 years.

Methods

Retrospective case-note review of patients undergoing laparoscopy with or without orchidopexy for impalpable testes.

Results

Eighty-three patients underwent laparoscopy. Twelve patients had bilateral impalpable testes; 25.3% of testes were identified intra-abdominally, 21% in the internal ring, and 29.5% of cases had vas and vessels entering the deep ring. A 76.5% success rate was achieved following diagnostic laparoscopy and standard open orchidopexy for testes in the region of the internal ring, compared to a 40.0% success rate following one-stage laparoscopic orchidopexy for ‘low’ intra-abdominal testes.

Conclusion

Laparoscopy is useful in managing patients with an impalpable testis from both a diagnostic and therapeutic standpoint. The success rate following laparoscopic orchidopexy in our non-paediatric specialist centre is lower than in most reports from paediatric specialist centres. This suggests the importance of centralization of such complicated, less frequently performed surgical procedures to a specialist centre.
