Penile replantation is uncommon, with most data being case reports or case series. In our setting, replantation is fairly new despite penile amputations being common as a result of marital disputes and assault. Replantation remains the most ideal option for managing these cases. We present a case of penile replantation in a 17-year-old male after traumatic amputation following an assault. Some of the challenges we encountered included loss of skin and the glans with formation of a hypospadias. Nevertheless, the outcome was satisfactory with return of sensation and erection.

Amputation of the penis is traumatizing to the patient, spouse, and family. Most cases of penile amputations documented result from self-mutilation, also known as Klingsor syndrome (1). Other causes include assault commonly by spouse, accidental amputation, circumcision, and iatrogenic (2,3). Various challenges facing penile replantation in developing countries include loss of the amputated part, lack of awareness on amputated part preservation and transportation by the public, poor referral systems, lack of equipment such as operating microscopes, and lack of microsurgical experts among others (4). Despite microsurgical penile reimplantation being an uncommon procedure, it is currently the ideal treatment option for penile amputation because it provides better sensory and erectile function than non-microsurgical techniques (2,4,5).

Case Report 

A 17-year-old male was referred to our facility after assault by people known to him with machetes in what was reported as a family feud. During the assault, he had his penis amputated by a machete and also sustained laceration to his left ear and the left half of the parietal scalp. The amputated part was stored directly in ice, and pressure was applied on the stump with a piece of cloth. He was rushed to the hospital, which was 2 hours away. At the hospital, the patient arrived with reduced level of consciousness. He was given tetanus toxoid, analgesics, and antibiotic. A unit of blood was transfused, and his scalp and ear lacerations were sutured. Hemostasis of the stump was achieved by clamping the vessels using artery forceps (Figure 1). The stump was wrapped in moist gauze, stored in a plastic bag that was stored in a cooler box with ice packs (Figure 2). After the stabilization, he was referred to our facility, which was 2 hours 15 minutes away. He presented 8 hours after the assault to our facility. He had no pre-existing medical condition and was neither a smoker nor user of any health risk substance. The patient was stabilized and prepared for the emergency procedure. The parent was counselled on the replantation procedure, and they fully consented. The patient was then taken to the theater 2 hours after arrival and 10 hours post-amputation.


Patient was placed under general anesthesia, and a suprapubic cystostomy was performed by the urology team (Figure 1). The stump was then exposed, revealing a clean cut at the proximal penile shaft (Figure 1).

The stump and amputated part were both prepared by cleaning them with saline using a syringe and gauze, then the edges were freshened to remove any damaged tissue and debris. The structures identified were the urethra,  corpora  carvenosa  and  spongiosumthe

superficial vein, and the deep dorsal vein, arteries, and nerves (Figure 3). The superficial vein was heavily crushed and could not be salvaged. The rest of the neurovascular bundles were freshened and prepared for anastomosis.

Anastomosis of the penile urethra was performed using interrupted Vicryl 5.0 and a catheter passed through the urethra. Next, the tunica albuginea was approximated using Vicryl 3.0. The dorsal arteries then the dorsal veins were anastomosed, and finally, the dorsal nerves were co-opted all using nylon 9.0 interrupted sutures. Deep and superficial fascias were closed as a single layer with Vicryl 3.0. Glove drain was left in-situ, and the skin was closed (Figure 4). Light dressing was applied with gauze.

Post-operatively, we transfused 3 units of blood and gave paracetamol, morphine, and tramadol for analgesia. We used enoxaparin (Clexane; Aventis Pharma Ltd., Midrand, Gauteng, South Africa) and aspirin for anticoagulation. Monitoring was done every 2 hours, and post-operative congestion was noted at 20 hours. The patient was taken back to theater for exploration.

At exploration, hematoma was noted and evacuated. The anastomoses were all intact. The patient was taken back to the wards where monitoring and treatment continued. Darkening of the glans and skin was noted on post-operative day 5, and we decided to let it demarcate. We debrided on post-operative day 17, losing the glans and skin of the penis. The wound was cleaned and dressed until good granulation was achieved (Figure 5). Notably, the patient had also developed hypospadias (Figure 5).Split-thickness skin grafting was done with 100% take

(Figure 6).

At 6 months post-replantation, the patient has 7cm of erect penile gland and reported good sensation at the tip (Figures 7 and 8). The main complication reported at 6 months was hypospadias, causing a spraying urinary stream.

The evolution of penile replantation has come a long way since the first reported case by Ehrich in 1929 (6) to the first successful reports of microsurgical penile replantation by Tamai et al. (7)and Cohen et al. in 1977(8). Prior to this, replantation was mainly done as a graft, or reconstructive options were offered to the patient. Engelman et al. (9) reported their experience with two cases and proposed that microsurgical replantation be the most ideal option for managing these patients, being superior to other plastic surgery reconstructive options. As advances in microsurgical techniques continue, outcomes keep improving, but complications still occur.Published data are case reports supporting the rarity of replantation(2,4). In our setting, the main cause of penile amputation is assault by spouse, and the main challenge we always face is that the amputated part is usually thrown away and patients present without it; this is also seen in many other settings in developing countries like ours(2,4). Our patient presented to us and had taken all the necessary precautions to preserve the amputated part.One of the challenges we face in the third world is the lack of knowledge on how to preserve the amputated part; furthermore, ice may not be readily available. Another challenge is crushing of the vessels with instruments prior to referral for hemostasis, as seen with our case, which lead to shortening of the vessels. The superficial vein was unsalvageable, and this is one of the postulated reasons for the congestion and loss of skin and the glans in our case. The other challenge in our setting is the lack of a microscope; we used loupe magnification 3.5 for the assistants and 4.5 and 7 for the surgeons, as was done by El harrech et al.(10) in their cases.Microsurgical neurovascular replantation offers the best outcomes in penile replantation compared with non-microneurovascular repair in terms of erectile function, return of sensation, aesthetics, and complications(11). Even with the best microsurgical technique, complications still arise, as in our case, which we re-explored, and despite the anastomosis being patent, complications still occurred, as was experienced by Landström et al.(5) in their literature review. Some of our complications of skin necrosis and loss of the glans were also seen by Wyczółkowski et al.(12). Most literature reports burying of the granulated penis in the scrotum, but in our case, we performed a thick split-thickness skin graft without complication of contraction (9,12). The patients also had hypospadias as a complication, as opposed to the strictures and fistulas that have been commonly reported (12).


Despite  the   challenges  we   face  in   our  settings,microsurgical replantation remains an ideal option. The higher the volume a center does, the better the outcomes;nonetheless complications still occur, and it is important to discuss this with your  patient. Education of  both patients   and   primary   care   physicians   improves outcomes,  as  in  our  case,  with  the  amputated  part preserved well by the patient’s next of kin collectively for the systemic component of the disease.
