“…Oral mucosa is also used in the reconstruction of ureteral stricture ( 31 ). Recently, Liang et al reported their results of 41 cases of ureteroplasty with lingual mucosa, which proved the universality and effectiveness of oral mucosa ( 32 ). As all of these materials gives good results in the urethral stricture treatment, the selection of specific materials is determined according to the specific clinical conditions and the wishes of patients.…”

Female urethral stricture is currently a challenging situation. In general, urethra dilatation can be selected for treatment, but the complications and high recurrence rate urge doctors to consider other treatments. Recently, dorsal oral mucosa graft urethroplasty is concerned by more and more surgeons, but there are not enough reports so far. A comprehensive search of dorsal oral mucosa graft urethroplasty was performed. According to the existing literature, there are applications of buccal mucosa and lingual mucosa, and compared with other kinds of grafts, the success rate is higher. However, there is a lack of multicenter, large sample and long follow-up studies. And there is still no enough comparative study between different types of oral mucosa. In summary, dorsal oral mucosa graft urethroplasty is an effective option for the management of female urethral stricture. More multicenter and large sample studies with long-term follow-up data are needed.

“…The tissue selection for ureteral ap-plasty should be based on the characteristics of the ureteral stenosis and the patient's overall condition, as well as related complications at the donor site and the functional outcomes at the reconstruction site [25]. In recent years, with the rise of laparoscopy and robotics, an increasing number of urological centers are using minimally invasive techniques for ureteral reconstruction [8,[26][27][28][29][30].…”

Background Surgical management of long ureteral stenosis is challenging. We describethe different modalities used in our center to treat long ureteral stenosis and report ourlong-term results. Methods This is a 17-year retrospective study to evaluate the efficacy of ureteroplasty with different surgical procedures in 12 patients with long ureteral stenosis. This study has passed ethical approval. Data were collected between May 2005 and September 2021. The mean age was 41 years. Recurrent stenosis was treated with long-term ureteral stent placement. The main observation index was the success rate of surgery. The secondary index was the rate of surgical complications and recurrent stenosis. The mean is used to describe parametric continuity variables, and the median and quartile range (IQR) are used to describe nonparametric continuity variables. Results Twelve patients were included. There were iatrogenic injuries in nine patients (75%), bilateral polyps in one (8.3%), ureteral occupation in one (8.3%), and unknown origins in one (8.3%). Ileal replacement was performed in three (25%) patients, lingual mucosa grafts in four(33.3%) patients, and boari bladder flaps in five (41.7%) patients. One of the surgeries was performed laparoscopically. The median follow-up was 49 months (range 8-204), and three patients (25%) had major postoperative complications. One patient’s treatment failed, requiring special reintervention, and two patients (16.7%) underwent ureteral stent placement. We accept the limitations of this small retrospective single-surgeon series, where the surgeon had a certain surgical selection preference. Conclusion Iatrogenic injury is the most common cause of long ureteral stenosis.There are many surgical methods for ureteral reconstruction, and the boari bladder flap is a preferred method for repairing long ureteral stenosis due to fewer postoperative complications and a low treatment failure rate.

“… 4 Recently, Liang et al . reported 41 cases of using a lingual mucosal graft instead of a BMG 10 ; 40 cases were operated by laparoscopy. In their cases, all patients underwent nephrostomy, and the DJ stent was removed 2 weeks before surgery, reducing ureteral swelling.…”

Laparoscopic redo pyeloplasty with a buccal mucosal graft

et al. 2022

View full text Add to dashboard Cite

Introduction: Redo pyeloplasty can be difficult due to scar tissue or fibrosis. Ureteral reconstruction with a buccal mucosal graft is performed safely and successfully, but most reports of ureteral reconstruction using a buccal mucosal graft are of robotassisted surgery, with few reports of laparoscopic-assisted surgery. A case of laparoscopic-assisted redo pyeloplasty using a buccal mucosal graft is presented. Case presentation: A 53-year-old woman was diagnosed with ureteropelvic junction obstruction, and a double-J stent was placed to relieve backache. She visited our hospital 6 months after double-J stent placement. Three months later, laparoscopic pyeloplasty was performed. At 2 months postoperatively, anatomic stenosis occurred. Holmium laser endoureterotomy and balloon dilation were performed; however, the anatomic stenosis recurred, and laparoscopic redo pyeloplasty with a buccal mucosal graft was performed. After redo pyeloplasty, obstruction was improved, and her symptoms disappeared. Conclusion: This is the first case of using a buccal mucosal graft for laparoscopic pyeloplasty in Japan.
