Boomerang Technique, The Buccal Mucosal Grafting Harvesting Model for Long Urethral Stricture Urethroplasty; A Case Series

PURPOSE

Currently, three methods are implicated in cases of long urethral stricture including harvesting buccal mucosa of inner cheeks, harvesting lip mucosa and finally lingual mucosal graft. This study evaluated the feasibility, safety and morbidity of our "Boomerang shape" technique used for graft retrieval from the inner cheeks to repair long urethral defect cases which are usually 12-15 cm in length and 2.5 cm in width.

MATERIALS AND METHODS

The Kilner-Doughty mouth retractor is inserted to give access to the donor site. Initially, the internal surface of the right/left cheek is cleaned with a solution containing 10% povidone-iodine. Then, Stensen's duct, located at the level of the second molar is identified and the desired size of the graft is measured and marked in a boomerang shape, 1.5 cm from the Stensen's duct and 1.5 cm from the edge of the cheek. To decrease submucosal bleeding from the harvest site, 1% lidocaine combined with a 1:100,000 epinephrine solution is injected using a 25-gauge long needle. The outlines of the graft are drawn by using a scalpel through the mucosa. Then, the outlined graft is sharply dissected and removed, leaving the muscle intact. A 5-0 polyglactin continuous suture is used for the closure of the harvest site. The standard graft harvested from the cheek should be 12-15 cm in length and 2.5 cm in width.

RESULTS

Between 2017-2019, five adults have had their mucosal grafts harvested by the "Boomerang shape" technique in our center. No donor site complications were observed. Moreover, no urethral strictures or diverticulum occurred and the functional outcomes were satisfactory in all patients.

CONCLUSION

Our routine technique of harvesting the buccal mucosa from the cheek is secure and easily performable by any surgeon. It has minimal incidence of intra and post-operative complications.

Penile fracture epidemiology, diagnosis and management in Iran: a narrative review

Penile fracture (PF) is considered an emergency in urology. In the literature there are some case series reporting considerable incidence of PF in some parts of Iran. There are no accurate data about the incidence of PF all around Iran. Although it may be uncommon in other parts of the country and in the other countries, it can also be underreported. There are some challenges in diagnosis, management, and also reporting of these cases. In this review of Iranian medical literature, we searched for penile fracture and penile injury keywords in Medline, Scopus, SID, Google and Persian medical journals. We reviewed the status of epidemiology, etiology, diagnosis, management and complications of PF in different parts of Iran in the published literature. To collect more accurate data, we also performed a questionnaire-based study with sending questionnaires by emails to 700 urologists throughout the country with 14% response rate. Incidence of PF varies significantly in different parts of Iran. Western province of Kermanshah has a significantly higher rate of PF. Adding data from different regions of Iran, we calculated that incidence of PF in Iran can be estimated between 1.14 to 10.48 per 100,000 of male populations, most probably closer to lower end. Although the incidence of PF varies significantly in different geographical areas, urologists practicing in Iran on average may encounter a PF patient every 3.5 months. To diagnose PF, majority of reviewed studies relied on history and clinical examination and did not recommend imaging except in patients with possible urethral injuries. Immediate surgical intervention can make good functional results with low morbidity and short hospital stay. Delayed surgical intervention and observational management approaches need large population studies with long term follow up.

Six years' experience of laparoscopic varicocelectomy using bipolar electrosurgery and its effect on semen parameters

PURPOSE

To evaluate postoperative results of laparoscopic varicocelectomy using bipolar electrosurgery and analyze semen according to the grade of varicocele after surgery.

MATERIALS AND METHODS

In a six-year period, 416 men with clinical varicocele and impaired semen parameters or infertility underwent laparoscopic varicocelectomy using bipolar electrosurgery. All patients were assessed for hydrocele and recurrence of varicocele six months and one year after the procedure. Semen analyses were obtained before and after the surgery and were compared according to the clinical grade of varicocele.

RESULTS

Seven patients (1.7%) had right side, 391 (94%) had left side and 18 (4.3%) had bilateral varicoceles. Varicocele grades I, II and III were detected in 113 (27.1%), 232 (55.7%) and 71 (17%) patients respectively. Abdominal wall emphysema and pneumoscrotum were developed in 19 (4.5%) and 11 (2.6%) cases. Recurrence rate was significantly higher in grade III varicocele (P < .001). In patients with varicocele grades of I and II, sperm concentration, motility and morphology significantly improved six months after surgery (P < .05). In patients with grade III varicocele, only sperm concentration improved (P < .05). Sperm motility and morphology did not show any significant change after one year.

CONCLUSION

Laparoscopic varicocelectomy using bipolar cautery is a safe, feasible and cost-effective technique with few complications. It significantly improves sperm parameters. A follow up program for at least one year after the surgery seems reasonable to detect recurrent cases. The study shows that increase in clinical varicocele grade can cause irreversible deleterious effects on sperm motility and morphology. So, earlier treatment is recommended.&nbsp.
