Testicular PAIN After Orchiectomy

A. Lee Dellon, Plastic Surgery, Johns Hopkins University, Towson, MD


Orchiectomy is done for tumor, infection, torsion, and trauma. When testicular pain persists after orchiectomy, or after other peritesticular procedures such as vasectomy or epididymectomy, the differential diagnosis must include neuroma of the genitofemoral nerve. Nine patients are presented with persistent pain after orchiectomy who were successfully treated by resecting the genitofemoral nerve, placing the proximal end below the pelvic brim. Eight of these patients would have had conservation of their testis if a neural origin had been considered prior to orchiectomy.


From July of 2009 through June of 2013, using our office computer database, nine patients were identified who had an orchiectomy but had persistent testicular pain. One man had a seminoma, but the other 8 had orchiectomy as the primary approach to treating testicular pain after vasectomy (3 men) or herniorraphy (5 men). Patient mean age was 44.3 years (range 25 to 78 years). Mean duration of pain from the index surgical procedure was 25.5 months (range 16 to 48 months). Diagnosis was demonstrated by physical examination with the trigger point being at the external inguinal ring duplicating the pain. Surgical approach exposed the external ring, retracted the spermatic cord or its remnant medially, and identified the 1 to 1.5 mm genitofemoral nerve posterior and lateral to where the spermatic cord was or would have been. The proximal end of the genitofemoral nerve was resected so that it dropped into the pelvis. Surgery was on the left side in 6 and right side in 3 men. The surgical technique will be demonstrated with intra-operative photographs. There were no post-operative complications.


Outcome data is available on 6 patients with a mean follow-up of 20.1 months (range 12 to 36 months). Three patients are less than 6 months, but are included for demographic purposes. Five of the six men had excellent relief and one good relief of their pain in the long-term group. To date, all 3 of the short-term group have excellent pain relief.


Testicular pain is transmitted via the genitofemoral nerve. Once intrinsic, organic testicular disease has been treated, persistent testicular pain should be considered as due to the genitofemoral nerve, which can be resected with high expectation of long-term pain relief. Eight of the nine patients reported here would have been sparred orchiectomy if a neural origin had been considered in the differential diagnosis.

American Society for Peripheral Nerve meeting in Hawaii

At the 2014 American Society for Peripheral Nerve meeting in Hawaii, on January 11, Drs Wyndell Merritt (on the left), from the Medical College of Virginia, in Richmond, Virginia, A. Lee Dellon (center), Johns Hopins University in Baltimore and Gedge D. Rosson (on the right), also from Johns Hopkins In Baltimore participated in an Instructional Course on the treatment of Complex Regional Pain Syndrome (CRPS). This used to be called "Reflex Sympathetic Dystrophy". Dr Dellon introduced the members and presented the current concept of Central Sensitization, the underlying problem in the Central Nervous System that predisposes some people to get CRPS. Dr Merritt discussed the non-operative approaches to treating CRPS. Finally, Dr Rosson presented the outcome study on the patients that he and Dr Dellon operated on with this problem.

CRPS of the upper or lower extremity: surgical treatment outcomes.

The hypothesis is explored that CRPS I (the "new" RSD) persists due to undiagnosed injured joint afferents, and/or cutaneous neuromas, and/or nerve compressions, and is, therefore, a misdiagnosed form of CRPS II (the "new" causalgia). An IRB-approved, retrospective chart review on a series of 100 consecutive patients with "RSD" identified 40 upper and 30 lower extremity patients for surgery based upon their history, physical examination, neurosensory testing, and nerve blocks. Based upon decreased pain medication usage and recovery of function, outcome in the upper extremity, at a mean of 27.9 months follow-up (range of 9 to 81 months), gave results that were excellent in 40% (16 of 40 patients), good in 40% (16 of 40 patients) and failure 20% (8 of 40 patients). In the lower extremity, at a mean of 23.0 months follow-up (range of 9 to 69 months) the results were excellent in 47% (14 of 30 patients), good in 33% (10 of 30 patients) and failure 20% (6 of 30 patients). It is concluded that most patients referred with a diagnosis of CRPS I have continuing pain input from injured joint or cutaneous afferents, and/or nerve compressions, and, therefore, similar to a patient with CRPS II, they can be treated successfully with an appropriate peripheral nerve surgical strategy.

Dr Dellon will be given an Honorary Professorship in Orthopedic Surgery at the 4th Military Hospital in Xi'an.

Before going to Xi'an, Dr Dellon will be in Shanghai and then in Beijing (Peking). In Shanghai, he will be Visiting Professor in the Department of Orthopedic Surgery at Fudan University in Shanghai, where he will speak on his work with neurolysis for diabetics with neuropathy and nerve compression. He has trained surgeons from this University and they will begin peripheral nerve surgery at their hospital. Dr Dellon will receive an Honorary Professorship in Orthopedic Surgery at Fudan University, where Dr Professor Feng Zhang is Chairman of Orthopedic Surgery. Dr Zhang is also the Editor of the journal, Microsurgery.
