Experience with arteriovenous fistula creation for maintenance hemodialysis in a tertiary hospital in South-Western Nigeria.

End-stage renal disease (ESRD) is prevalent in our region. A major mode of treatment is by maintenance hemodialysis, and reliable vascular access is paramount for this to be successful. Arteriovenous fistula (AVF) creation offers permanent vascular access in patients with ESRD. We present our experience on AVF creation over a 10-year period. Our objective was to retrospectively review the outcome of all cases of AVF that have been created for ESRD patients at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife Nigeria between January 2006 and December 2015. The demographic characteristics, indications, clinical and intraoperative findings, operative complications and outcomes were filled into a pre-designed proforma. A total of 80 cases were reviewed. The age range was 17-80 years, with a mean of 49.03 ± 16.34 years. Males (85%) were more common than females (15%). Chronic glomerulonephritis and hypertension accounted for about 77.5% of etiology of ESRD in these patients. The left (non-dominant) upper limb was used in 88.1% of cases whereas 11.9% were created on the right upper limb. The distal radio-cephalic AVF (76.3%) was most commonly performed; with either the end (vein) to side (artery) (68.8%) or side-to-side (31.2%) anastomotic techniques employed. There was a primary failure in six patients (7.5%). Primary failure was more common in diabetics and thrombosis (7.5%) was the most common cause for primary failure. AVF creation has very good outcome in well-selected patients.

Surgical Reconstruction of Giant Penoscrotal Lymphedema in Sub-Saharan Africa.

OBJECTIVE: To present management challenges, surgical technique, and outcome associated with penoscrotal reconstruction in patients with giant scrotal lymphedema in sub-Saharan Africa. METHODS: A prospective study of all patients who had penoscrotal reconstruction for giant scrotal lymphedema at our university teaching hospital between January 2003 and December 2012 was carried out. Patients' preoperative clinical evaluation findings, operative technique, and postoperative course were reviewed after obtaining ethical approval and informed consent from the patients. RESULTS: Nineteen patients with giant scrotal lymphedema presented to us during the period of study; out of which, 11 had surgical excision and were studied. Their mean age and median duration of symptoms were 48.5 years and 11.5 years respectively. They all had surgical reconstruction using modified Charles procedure by the same combined team of urologists and plastic surgeons. Scrotal hematoma (27.3%) and superficial surgical site infection (18.2%) were complications encountered postoperatively. One patient (9.1%) had recurrence within 24 months, requiring repeat excision. CONCLUSION: Giant scrotal lymphedema poses severe physical challenge to the sufferer. Surgery remains the only hope to reduce penoscrotal size. Combined effort of urologic and plastic surgeons is essential for reconstruction.
