Background: Hydrocele is abnormal collection of serous fluid in the tunica vaginalis or a patent processus vaginalis. It is commonly encountered in our practice and often requires surgical treatment. However in our setting and in many underdeveloped countries, availability of general anaesthetic service is poor due to lack of trained personnel and equipment. Objectives: To ascertain the practicability and acceptability of hydrocelectomy under sedation and local anaesthesia in Nigerian adults with hydrocele Patients and Methods: A prospective study was carried out over a two year period on patients that had hydrocelectomy at the surgery unit of the Obafemi Awolowo University Teaching Hospitals Complex,Wesley Guild Hospital, Ilesa. Consecutive patients with diagnosis of hydrocele who consented had hydrocelectomy using intramuscular diazepam sedation and spermatic-cord block with 0.5 % plane xylocaine and the scrotum infiltrated with same along the line of incision. Results: Fifty adult patients were studied: age range 15-94 years. Eighty percent of the patients had unilateral hydrocele and the commonest type was vaginal hydrocele (94%). All patients had hydrocelectomy, 96 % were under local anaesthesia while 4 % were converted to general anaesthesia. All patients except one prefer to have future surgery under such local anaesthesia and sedation. Conclusion: Hydrocelectomy under local anaesthesia and sedation is practicable and was tolerated and accepted by the adults patients studied
