Hi there ! Good evening. I am Dr Shareef answering your query. Your husband must have had an open prostate surgery (not a transurethral one) which could result in a hernia in the incision site. This could result due to very many factors, like a week musculature, or a post operative infection, due to chronic cough/constipation resulting in increased intra abdominal pressure or due to dehiscence of the suture line due to inability of the suture to hold both side of the incision in place. This would need an elective surgery which would close the defect and strengthen the musculature with a synthetic mesh. This could also be done by a laparoscopic method in competent hands and results are usually good. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef.
