A preliminary clinical study of endoscopic minimally-invasive surgery in urethral stricture complicated with false passage

Abstract Background To investigate the current diagnostic and therapeutic approaches to anterior urethral strictures of Chinese urologists and to compare with developed countries and the American Urologic Association guidelines. Methods Anonymous questionnaires were distributed to members of Official Wechat Account of urology from March 19, 2020 to April 10, 2020. Descriptive and multiple correspondence analysis were used to analyze the data. Results A total of 1276 online questionnaires were received. The response rate was 21.7% (1276/5878). The most common diagnostic methods for anterior urethral stricture were urethrography (90.7%) and urethrocystoscopy (85.4%), while urethral dilation (92.3%) and internal urethrotomy (60.1%) were the main therapeutic procedures. End-to-end urethroplasty (45.2%) was the most common open surgery, followed by skin flap urethroplasty (14.9%) and free graft urethroplasty (12.4%). 76.2% of urologists used urethroplasty only after the failure of minimally invasive surgery (reconstructive ladder treatment strategy). Furthermore, middle-aged or elderly urologists who had attended trainings, had senior practice roles, and who utilized a reconstructive ladder treatment approach were most likely to perform urethroplasties. Conclusions Anterior urethral stricture treatment in China is still dominated by minimally invasive surgery, with most urologists using the reconstructive ladder treatment strategy. In general, the overall diagnostic and therapeutic strategies were similar between China and developed countries, with some deviations from the American Urologic Association guidelines.

Minimally invasive surgery (MIS) using the erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser (Waterlase MD, Biolase, Irvine, CA) to treat moderate to advanced periodontal disease is presented as an alternative to conventional therapies. To date, there are few short- or long-term studies to demonstrate the effects of this laser in treating and maintaining periodontal health. Electronic clinical records from 16 patients – total of 126 teeth, with pocket depths ranging from 4 mm to 9 mm – were treated with the same protocol using the Er,Cr:YSGG laser. The mean baseline probing depths (PD) were 5 mm and clinical attachment levels (CAL) were 5 mm in the 4 - 6 mm pretreated laser group. The mean baseline probing depths were 7.5 and 7.6 mm for PD and CAL respectfully in the 7 – 9 mm pretreatment laser group. At the 2 year mark, the average PD was 3.2 ± 1.1 mm for the 4-6 mm pocket group and the 7-9 mm pocket group had a mean PD of 3.7 ± 1.2 mm. mean CAL was 3.1 ± 1.1 mm for the 4-6 mm group and 3.6 ± 1.2 for the 7-9 mm group with an overall reduction of 1.9 mm and 4.0 mm respectively. At one and two years, both groups remained stable with PD comparable to the three-month gains. The CAL measurements at one and two years were also comparable to the three-month gains.
