Publication Buccal Mucosal Graft Urethroplasty for Complex Urethral Strictures: A Single Center Study(Institute of Medicine, 2023) Chalise, Pawan R; Luitel, Bhojraj; Chapagain, Suman; Poudyal, Sujeet; Pradhan, Manish M; Parajuli, Purushottam; Sharma, Uttam K; Gyawali, Prem RABSTRACT Introduction: Urethral strictures have been a surgical challenge for the reconstruction urologists. Lichen sclerosus is the most common cause of urethral stricture in the developing world. There are different free graft tissues for urethroplasty but buccal mucosal graft (BMG) urethroplasty is an effective and versatile procedure for inflammatory and long segment urethral strictures. Methods: A total of 64 cases who had complex urethral strictures underwent dorsal onlay BMG urethroplasty. BMG was harvested from cheeks or sublingual mucosa depending upon the length of the stricture. The catheter was removed after 3 weeks and patients were evaluated with uroflowmetry. The surgery was considered successful if subjective and objective parameters were satisfactory. Results: Average length of the harvested graft was 14.5 cm (10-18 cm) in 42 panurethral, eight distal penile, four proximal penile and bulbar, and 10 bulbar urethral strictures. Postoperative period was uneventful except in four, of which two developed urethral fistulas and the other two developed periurethral abscess which resolved after treatment. After catheter removal, all voided with satisfaction. All patients, reassessed after mean period of 21 months, had satisfactory voiding. Two patients underwent visual internal urethrotomy for stricture at proximal site of BMG placement. There were no complications observed in the donor site with complete healing in all. Conclusion: Dorsal onlay BMG Urethroplasty is an effective and versatile procedure for anterior urethral strictures with excellent results and with minimal donor site morbidity.

This study aimed to identify demographic parameters, clinical characteristics, and surgical management of pediatric urolithiasis in a tertiary care center in Nepal. Methods: This was a retrospective and descriptive study of pediatric patients (≤18 years) who underwent surgical management of urolithiasis in the Department of Urology and Kidney Transplant Surgery, Tribhuvan University Teaching Hospital from January 2021 to December 2022. Results: Total 64 patients with Male: Female ratio 1.78:1 and mean age of 8.63±5.56 years presented mostly with pain abdomen (93.8%) followed by lower urinary tract symptoms (26.6%), hematuria (20.3%), and fever (14.1%). The mean number of calculi was 2.2±1.47 and the mean size was 13.97±8.30 mm. Most of the calculi (39.1%) were in the right system and 90.62% were in the upper tract. Only 15.62% of patients had calculi in the lower tract. Open surgeries were performed in only 10.93% and the rest were managed by minimally invasive procedures. Percutaneous nephrostomy tube insertion was done in 6 (9.37%) of patients and 1 (1.56%) underwent nephrectomy for nonfunctioning kidney. Conclusion: Pediatric urolithiasis patients presented with pain abdomen, lower urinary tract symptoms, or hematuria. Surgical management has shifted from open surgeries in the past to minimally invasive surgeries at present. Keywords: Minimally invasive surgery; pediatric; urolithiasis
