Feasibility, Safety and Acceptance of Buccal Mucosa Harvest Under Local Anesthesia for Substitution Urethroplasty:Prospective Observational Study in a Tertiary Centre.

Background Urethral stricture is a challenging condition with significant socioeconomic impacts, often requiring surgical intervention such as urethroplasty. Buccal mucosa grafts (BMG) are a popular choice for substitution urethroplasty due to their favorable outcomes. This study evaluates the feasibility, safety, and acceptance of harvesting buccal mucosa grafts under local anesthesia. Objective To assess feasibility, safety and acceptance of Buccal mucosa harvest under local anesthesia. Method A prospective observational hospital based study to evaluate outcomes of substitution urethroplasty using buccal mucosa grafts (BMG) under local anesthesia. Result Of the 40 patients, 28 had unilateral graft harvests, while 12 had bilateral procedures. The mean graft length obtained was 5.65 cm. Postoperatively, patients experienced a quick recovery, with full mouth opening achieved within an average of 2.78 days and resumption of normal eating within 2.6 days. Minor complications included oral swelling in 15% of cases and food residue in 12.5%. Although 87.5% of patients reported pain at the perineal wound site, the overall pain score averaged 3.58, indicating manageable discomfort. Importantly, 92.5% of patients expressed a willingness to undergo the procedure again if necessary. Conclusion These findings suggest that buccal mucosa graft harvest under local anesthesia is both feasible and well-tolerated. The procedure appears to be a safe alternative to regional or general anesthesia, with minimal complications and a high level of patient acceptance. Future randomized controlled trials comparing local anesthesia to regional or general anesthesia could provide additional insights and further validate these findings. This study contributes to the growing body of evidence supporting the use of local anesthesia in urethral stricture surgery, offering a practical approach to managing this condition effectively.

The application of the "perinephric fat wrapping" technique with oral mucosal graft for the management of ureter repair and reconstruction.

OBJECTIVE: The management of long-segment ureteral stenosis has posed a significant challenge for urologists. Ureteroplasty with oral mucosal graft has emerged as an effective approach for treating long-segment ureteral stenosis and defects. A key step in replacement repair surgery involves suturing the surrounding tissue with an adequate blood supply around the reconstructed ureter. The current study aims to evaluate the potential practical application of the "perinephric fat wrapping" technique in laparoscopic ureteroplasty with oral mucosal graft. METHODS: Between July 2018 and February 2023, 26 patients with ureteral stenosis underwent laparoscopic ureteroplasty with oral mucosal graft at the Second Affiliated Hospital of Anhui Medical University. We used traditional omental wrapping technique (OW group) or perinephric fat wrapping technique (PFW group) to enhance ureter repair. Perioperative and follow-up data for both groups were collected retrospectively and compared. RESULTS: There were 10 patients in OW group, including 4 males and 6 females, with BMI of 23.5±2.8 kg/m2 and stenosis length of 3.6±1.6 cm. There were 16 patients in the PFW group, including 10 males and 6 females, with a BMI of 26.1±3.3 kg/m2 and a median stenosis length of 2.3 cm (range, 1.2~6.0 cm). The operation of both groups was successfully completed, and no serious complications occurred during the operation. The mean operating time (OT) in the OW group was 200.6±41.9 min, the estimated amount of blood loss (EBL) was 25 ml (range, 10~30ml), and the median length of postoperative hospital stay (LHS) was 7.5 days (range 4.0~14.0 days). In the PFW group, the mean operating time (OT) was 211.9±38.3 min, the estimated blood loss (EBL) was 25 ml (range, 5~150ml), and the postoperative hospital stay (LHS) was 6.8±2.0 d. There was no significant difference between the two groups in the above indexes. Postoperative anal exhaust time was 1.0 d (range, 1.0~2.5d) in the PFW group and 1.9±0.5 d in the OW group, with significant difference between the two groups (P=0.009). The mean follow-up time was 36.8±15.9 months, and there was no significant difference between OW group and PFW group in the curative effect of operation. CONCLUSION: Perinephric fat wrapping technique not only avoids the potential effects of using omentum on abdominal organs, it is also as safe and effective as omentum wrapping technique in repairing and reconstructing the ureter using oral mucosal grafts.

Successful Application of Buccal Mucosal Graft Transplant in Resistant Suture Exposure of Transscleral-Sutured Posterior Chamber Intraocular Lens.

We report the successful reconstruction of suture exposure with the oral mucosal graft in a patient with suture exposure after transscleral-sutured posterior chamber intraocular lens implantation. The 70-year-old patient had a history of vitreoretinal surgery and transscleral-sutured posterior chamber intraocular lens implantation after complicated cataract surgery. He was referred to our department because of suture exposure. The best-corrected visual acuity was 20/2000 OD and 20/50 OS. We observed exposed PC9 sutures from both the nasal and temporal conjunctiva in the right eye. The patient showed appearance of scleromalacia in the same regions, so scleral flap surgery was not considered. Despite both tenoplasty and amniotic membrane transplant procedures, exposure could not be controlled. Instead, the patient received oral (buccal) mucosal graft transplant to the resistant exposure areas. A single layer of protective amniotic membrane was transplanted over the buccal mucosal graft. This method resulted in effective control of the exposed area. In conclusion, an oral mucosal graft can be used in many ocular pathologies that require conjunctival reconstruction because of the simplicity of tissue excision from the mucosa, allowing adequate tissue excision, durability of the obtained tissue, and ease of use. Our case report highlights that resistant transscleral-sutured posterior chamber intraocular lens suture exposure can be successfully managed with oral mucosal grafting.

Combined Treatment of Tunnelled Composite Anterior-Lateral Inguinal Skin Flap, Buccal Mucosal Graft and Hyperbaric Oxygen Therapy for Catastrophically Lost Penis after Circumcision.

BACKGROUND: Catastrophic loss of the penis following post-circumcision necrosis is a rare and devastating complication. Treatment options are limited, and the process is highly challenging. This study aims to report the successful application of our combined treatment approach for a 6-year-old patient who experienced total penile loss due to progressive necrosis 1 year after circumcision. METHODS & RESULTS: Following penile degloving, proximal penile mobilisation and separation and reshaping of the corpora were performed. The penile shaft was covered with a tunnelled composite anterior-lateral inguinal skin flap. Glanuloplasty was performed using a left buccal mucosal graft, followed by 10 sessions of hyperbaric oxygen therapy. At 1.5 months postoperatively, urethral dilation was performed once because of minor voiding difficulties. At 10 months postoperatively, the patient had excellent voiding function and no additional complaints. The patient expressed high satisfaction with the outcome and is still under close follow up. CONCLUSIONS: A standard treatment for serious complications such as necrosis and total penile loss has not been established yet. Although scrotal skin flap is a straightforward technique, it was not preferred in our case because of fibrosis following scrotal necrosis and potential risk of hair growth. The developed approach could be an effective alternative to other techniques.

Xenogeneic Collagen Matrix Versus Free Gingival Graft for Augmenting Peri-Implant Keratinized Mucosa Around Dental Implants: A Systematic Review and Meta-Analysis.

OBJECTIVES: There is a growing evidence to suggest augmenting peri-implant keratinized mucosa in the presence of ≤ 2 mm of keratinized mucosa. However, the most appropriate surgical technique and augmentation materials have yet to be defined. The aim of this systematic review and meta-analyses was to evaluate the clinical and patient-reported outcomes of augmenting keratinized mucosa around implants using free gingival graft (FGG) versus xenogeneic collagen matrix (XCM) before commencing prosthetic implant treatment. MATERIAL AND METHODS: Electronic databases were searched to identify observational studies comparing implant sites augmented with FGG to those augmented with XCM. The risk of bias was assessed using the Cochrane Collaboration's Risk of Bias tool. RESULTS: Six studies with 174 participants were included in the present review. Of these, 87 participants had FGG, whereas the remaining participants had XCM. At 6 months, sites augmented with FGG were associated with less changes in the gained width of peri-implant keratinized mucosa compared to those augmented with XCM (mean difference 1.06; 95% confidence interval -0.01 to 2.13; p = 0.05). The difference, however, was marginally significant. The difference between the two groups in changes in thickness of peri-implant keratinized mucosa at 6 months was statistically significantly in favor of FGG. On the other hand, XCM had significantly shorter surgical time, lower postoperative pain score, and higher color match compared to FGG. CONCLUSIONS: Within the limitation of this review, the augmentation of keratinized mucosa using FGG before the placement of the final prosthesis may have short-term positive effects on soft tissue thickness. XCM might be considered in aesthetically demanding implant sites and where patient comfort or shorter surgical time is a priority. The evidence support, however, is of low to moderate certainty; therefore, further studies are needed to support the findings of the present review.

Bulbar urethroplasty techniques and stricture recurrence: differences between end-to-end urethroplasty versus the use of graft.

Urethral stricture (US) affects most commonly the anterior portion of the urethra, concretely the bulbar, with a significant incidence in men. Open urethroplasty is the gold standard treatment. However, stricture recurrence (SR) remains a current subject of concern. The aim of the present review is to provide an updated literature summary on surgical urethroplasty techniques for bulbar US and prognostic factors for SR, comparing the different approaches. For short strictures, excision and primary anastomosis (EPA) is the preferred option, with success rates exceeding 90%. Substitution techniques are usually required for longer strictures (>2-3cm). Buccal mucosa graft (BMG) remains the first choice as it complies with ideal features, with no significant differences regarding the site of graft implantation. Stricture length, time since urethroplasty and number of previous urethral interventions are risk factors for failure. Also, surgeon's experience affects technique selection and future outcomes. There seems to be consensus on a higher SR rate following substitution techniques compared to EPA, which appears to be influenced by the stricture length, usually longer in the former group. Furthermore, there is a trend in favor of endoscopic management of SR, except for long and complex recurrences where grafts should be used. In conclusion, multiple urethroplasty techniques are available and selection must be carefully individualized, focusing on stricture characteristics, patient's history, and surgeon's experience. Well-designed studies with clear definitions and follow-up protocols are still necessary to develop standardized guidelines on the management of bulbar US.

A novel surgical technique to resolve mucosal fenestration of a root apex: Apical tunnel surgery: A case report.

RATIONALE: Endodontic surgery, which includes apex resection, retro-fill and some regeneration procedures, is a traditional way to deal with apex fenestration. The endodontic surgery could bring large flap, curtate root length, non-healing mucosa and soft tissue deficiency in the apex area. Other treatment options might be considered according to different etiological factors. Mucogingival surgery provides some ideas in accumulation of soft and hard tissues, especially some unique methods such as "tunnel technique" bringing us a view of minimal invasive surgery approach. A novel surgery named "apical tunnel surgery" was reported here to resolve a root apex exposure with the tunnel-like technique. PATIENT CONCERNS: A young female complained about root exposure of upper right anterior tooth without history of trauma or orthodontic treatment. DIAGNOSIS: The intraoral examination revealed a buccal root apex exposure about 3mm in diameter of #12 (FDI teeth numbering system). The tooth was slightly dark with Class 1 mobility. The periodontal situation was good and the occlusion check revealed no traumatic bite on #12. The cone-beam computed tomography (CBCT) showed a bone fenestration from the buccally lower 1/2 root surface to the apex and bone absorption around the apex. It also revealed a bone contour deficiency in #12 area. INTERVENTIONS: Root canal treatment, root surface debridement, and soft tissue combined with hard tissue accumulation were carried out in one tunnel-like surgery. OUTCOMES: Examination of 12-month follow-up showed a healed and thickened mucosa in the buccally apical region and CBCT showed the continuous lamina dura occupied the buccal aspect of #12 root apex. LESSONS: This new apical tunnel surgery provided soft and hard tissue accumulation in one minimal invasive way in the apex exposure case caused by bone fenestration and thin mucosa.

[Robot-assisted laparoscopic ureteroplasty with buccal mucosa graft for complex ureteral stricture].

OBJECTIVE: To investigate the feasibility, safety and effectiveness of robot-assisted laparoscopic buccal mucosa graft ureteroplasty in the treatment of complex long proximal ureteral stricture. METHODS: The clinical data of 20 patients with proximal ureteral stricture undergoing robot-assisted laparoscopic buccal mucosa graft ureteroplasty admitted to the Department of Urology, Peking University First Hospital and Beijing Jiangong Hospital from July 2022 to January 2023 were prospectively collected and analyzed. Intraoperative conditions, postoperative complications and follow-up data were also recorded and analyzed. RESULTS: The operations under robot-assisted laparoscopy were performed successfully in all the 20 patients without conversion to traditional laparoscopic surgery or open surgery. The study included 14 males and 6 females with a mean age of (41±11) years (range: 19 to 60 years) and a mean body mass index of (24.3±3.6) kg/m2 (range: 18.2 to 31.8 kg/m2). There were 9 cases on the left side and 11 cases on the right side. The strictures of all the patients were located in the proximal segment of the ureter (including the ureteropelvic junction). The mean preoperative serum creatinine was (92.2±23.3) µmol/L (range: 49.2 to 138.9 µmol/L), and the mean length of ureteral stricture was (2.8±0.9) cm (range: 1.0 to 4.0 cm). Ten patients had previously undergone unsuccessful reconstructive surgery. During the operation, 12 patients received posteriorly augmented anastomosis with ventral onlay. The mean length of the buccal mucosa graft harvested during the operation was (3.1±0.6) cm (range: 2.0 to 4.3 cm), and the median width was 1.5 cm (range: 1.0 to 2.0 cm). The omentum flap was used to wrap the reconstructed ureteral segment in all the 20 cases. The median operative time was 154 min (range: 113 to 300 min), and the median estimated blood loss was 45 mL (range: 0 to 100 mL). The median postoperative hospital stay was 4 d (range: 4 to 14 d). The mean postoperative follow-up time was (15.0±1.7) months (range: 12.5 to 17.9 months), and the surgical success rate was 100.0% in this study. After surgery, 11 patients reported mild discomfort at the oral donor site, 2 patients deve-loped urinary tract infection, and no postoperative complications were reported in the other 7 patients. The mean serum creatinine was (90.9±23.9) µmol/L (range: 60.0 to 153.0 µmol/L) six months after surgery. CONCLUSION: Robot-assisted laparoscopic buccal mucosa graft ureteroplasty for the treatment of complex long proximal ureteral stricture has satisfactory efficacy without severe complications, which has shown good feasibility, safety and effectiveness. However, large sample studies and long-term follow-up are still needed to evaluate its long-term efficacy.

Topographical and histological analysis of keratinized mucosal grafts removal techniques an ex-vivo study in porcine mandibles.

The aim of this study was to assess the surface and tissue quality of keratinized mucosa grafts (KMG) obtained using the conventional scalpel and mucotome techniques. This was an experimental in vitro/ex vivo study involving six porcine hemi-mandibles. Specimens were harvested using both the mucotome and conventional scalpel techniques, with randomization determining the choice of technique for tissue removal. The specimens were prepared following predefined laboratory protocols and subsequently subjected to optical microscopy for evaluating epithelial and connective tissue and scanning electron microscopy for topographical and 3D profilometry analysis. Tissues harvested using the mucotome exhibited a linear base and uniform thickness, along with the presence of submucosa and fibrous connective tissue, all of which are ideal for graft success. Differences in the surface characteristics of specimens obtained through the two techniques were observed during a comparative analysis of images obtained through both microscopy types. KMG obtained using the mucotome technique displayed greater uniformity and reduced undesirable cell presence compared to the scalpel technique, thereby enhancing the likelihood of success in soft tissue graft surgical procedures. This study provides valuable insights to oral healthcare professionals and may contribute to future research aimed at achieving more successful surgeries, shorter postoperative recovery times, reduced discomfort, and an overall more positive patient experience.

Current Trends in the Use of Buccal Grafts During Urethroplasty Among Society of Genitourinary Reconstructive Surgeons.

OBJECTIVE: To analyze current standards in urethroplasty by urologists employing buccal mucosal grafts (BMG) for treating urethral stricture disease (USD). METHODS: An IRB-approved online survey was distributed to members of the Society of Genitourinary Reconstructive Surgeons (GURS) between July and October 2022 to assess BMG utilization in urethroplasty. Questions covered surgeon experience, graft harvest site, graft length, surgical technique, and perceived success rates. RESULTS: Of 350 invited GURS members, 134 responded (38%). Sixty-nine percentage were GURS fellowship-trained, performing 10-30 urethroplasties annually. Ninety-five percentage harvested their own grafts, with 99% preferring buccal mucosa as the primary site. Buccal mucosa was favored over fasciocutaneous flap for penile urethroplasty, regardless of circumcision status (95% with, 84% without). For bulbar urethroplasty with BMG, dorsal graft placement was favored (66%) over ventral (34%). Most surgeons (90%) preferred multiple BMGs over combined graft/flap for panurethral strictures. When harvesting long grafts, 56% preferred using both cheeks. Anastomotic urethroplasty was preferred over buccal graft urethroplasty for short bulbomembranous stenosis post-radiotherapy (63% vs 37%). Surgeons reported a success rate of 80%-90% (53%). CONCLUSION: The expanded scope of reconstructive urology has led to increased use of BMG in diverse urethral reconstructions. Buccal grafts are now preferred for penile, bulbar, and panurethral strictures, demonstrating high perceived success rates in the reconstructive community.

Urinary and Oral Microbiota Among Men Undergoing Buccal Urethroplasty.

OBJECTIVE: To assess changes in the urinary microbiota after buccal urethroplasty. METHODS: At the University of California San Francisco, we enrolled 9 adult males with urethral strictures undergoing buccal urethroplasty where we collected urine and oral swabs intraoperatively and 3 months postoperatively. 16S rRNA sequencing was used to profile the microbiota. RESULTS: At baseline, the mouth contains twice the number of unique bacteria (alpha diversity) and the microbial community is significantly distinct compared to the urinary tract. Despite having a buccal mucosa in the urinary tract after urethroplasty, the number of unique bacteria in the urine remained stable. However, the bacterial community composition and structure significantly changed in the urinary tract with the enrichment of Corynebacterium genus at 3 months post-urethroplasty procedure. CONCLUSION: In this pilot study, we showed that the alpha diversity in the urinary microbiota did not significantly change despite having a buccal tissue with the capacity to support high bacterial diversity in the urinary tract. To our surprise, the post-urethroplasty urinary microbiota was not a hybrid of baseline oral and urine microbiotas; the changes detected, such as an enrichment of the Corynebacterium genus, were more nuanced yet could profoundly impact surgical outcomes like graft changes and stricture recurrence. Our study not only established the feasibility but also outlined a blueprint for conducting a large-scale study to assess alterations in the urinary microbiome in relation to surgical outcomes.

Update on using buccal myomucosal flaps for patients with cleft palate and velopharyngeal insufficiency: primary and secondary interventions.

PURPOSE OF REVIEW: This review aims to examine the indications and anatomical circumstances for when to optimally incorporate buccal myomucosal flaps (BMFs) into palatal surgical reconstruction. RECENT FINDINGS: Studies examining outcomes following primary cleft palate repair with incorporation of BMF have demonstrated excellent speech outcomes and low rates of fistula. Furthermore, some reports cite an association of buccal flap use with reduced midface hypoplasia and the need for later orthognathic surgery. When used for secondary speech surgery, BMFs have been shown to lead to speech improvements across multiple outcome measures. Advantages of BMF techniques over conventionally described pharyngeal flap and pharyngoplasty procedures include significant lengthening of the velum, favorable repositioning of the levator muscular sling, and lower rates of obstructive sleep apnea. SUMMARY: Although the published data demonstrate excellent outcomes with use of BMFs for primary and secondary palatal surgery, there are limited data to conclude superiority over the traditional, more extensively investigated surgical techniques. The authors of this review agree with the evidence that BMF techniques can be useful in primary palatoplasty for congenitally wide clefts, secondary speech surgery for large velopharyngeal gaps, and/or in individuals with a predisposition for airway obstruction from traditional approaches.

A combination technique of strip free gingival grafts and xenogeneic collagen matrix in augmenting keratinized mucosa around dental implants: a single-arm clinical trial.

BACKGROUND: The aim of this study was to assess the outcomes of the combination technique of strip free gingival grafts (SFGG) and xenogeneic collagen matrix (XCM) in augmenting the width of keratinized mucosa (KMW) around dental implants, and compare its efficacy with the historical control group (FGG). METHODS: Thirteen patients with at least one site with KMW ≤ 2 mm after implant surgery were included and received SFGG in combination with XCM. Another thirteen patients with the same inclusion and exclusion criteria from the previous trial received FGG alone. The same outcomes as the previous trial were evaluated. KMW, thickness of keratinized mucosa (KMT), gingival index (GI) and probing depth (PD) were measured at baseline, 2 and 6 months. Postoperative pain, patient satisfaction and aesthetic outcomes were also assessed. RESULTS: At 6 months after surgery, the combination technique could attain 3.3 ± 1.6 mm of KMW. No significant change could be detected in GI or PD at 6 months compared to those at 2 months (p > 0.05). The postoperative pain and patient satisfaction in VAS were 2.6 ± 1.2 and 9.5 ± 1.2. The total score of aesthetic outcomes was 3.8 ± 1.2. In the historical FGG group, 4.6 ± 1.6 mm of KMW was reported at 6 months, and the total score of aesthetic outcomes was higher than the combination technique (4.8 ± 0.7 vs. 3.8 ± 1.2, p < 0.05). CONCLUSIONS: The combination technique of SFGG and XCM could increase KMW and maintain peri-implant health. However, this combination technique was associated with inferior augmentation and aesthetic outcomes compared with FGG alone. TRIAL REGISTRATION: This clinical trial was registered in the Chinese Clinical Trial Registry with registration number ChiCTR2200057670 on 15/03/2022.

Repair of buccal mucosa and floor of mouth defects using keystone design perforator island flap.

OBJECTIVE: To assess the feasibility of utilizing the keystone design perforator island flap (KDPIF) for the repair of small to medium-sized defects in the buccal mucosa and floor of mouth (cT1-2 stage tumor). STUDY DESIGN: We conducted a retrospective analysis of eight patients who underwent KDPIF to address oral defects at the Affiliated Hospital of Qingdao University between June 2021 and September 2022. Patient information, including medical history, defect site, flap size, operative time, hospital stay, complications, and postoperative recovery of oral function, was comprehensively evaluated. RESULTS: Eight patients (6 females and 2 males) underwent reconstruction using KDPIF. The mean operation time was 58.5 minutes (55-63 minutes), with an average length of stay of 3.5 days (3-5 days). None of the 8 cases (100%) exhibited flap splitting necrosis or infection. Moreover, no scar contracture was observed, and oral functions, including the degree of opening, type of opening, tongue mobility, speech function, and swallowing function, were successfully restored. One patient (12.5%) experienced bleeding from the incision on the first postoperative day, but following compression, hemostasis was achieved, and the incision healed well. CONCLUSIONS: KDPIF demonstrates technical feasibility and suitability for repairing small to medium-sized buccal mucosa and floor of mouth defects (cT1-2).

Myomucosal composite graft: A simple technique for full-thickness vermilion defects of the lower lip.

Reconstruction of vermillion defects of the lower lip requires careful consideration of functional and aesthetic aspects. Traditionally, various local flap methods involving tissue advancement from the corner of the mouth, lateral chin, and medial cheek have been commonly employed to fill lower lip defects. However, these approaches have inherent limitations, which include technical complexity, disruption of the orbicularis oris muscle, lip tightening, microstomia, and visible scarring. To overcome these limitations, we employed a free myomucosal composite graft from the lower lip to reconstruct small to medium vermilion defects. Our technique is based on a simple and reproducible surgical approach that facilitates natural volume rearrangement of tissues. Moreover, this method enables precise inset and tension-free repair, prevents lip tightening, and offers excellent aesthetic outcomes with no vertical scarring and appropriate color matching with surrounding tissues.

Critically Evaluating the Role for Postoperative Antibiotics in Patients Undergoing Urethroplasty With Buccal Mucosa Graft: A Claims Database Analysis.

OBJECTIVE: To compare outcomes among patients undergoing first-time urethroplasty with buccal mucosa graft (BMG) who receive postoperative antibiotics vs those who do not. METHODS: A retrospective cohort study was conducted using the TriNetX claims database between 2008-2022. Using CPT, ICD10, and LOINC codes, patients >18 years old undergoing primary urethroplasty with BMG who received an outpatient prescription for antibiotics between postoperative day 0-30 or did not were queried. Patients with positive preoperative urine culture or urinary tract infection (UTI) within 30days preoperatively were excluded. Surgical outcomes included 5-year revision rates and revision-free survival. Safety outcomes included new UTI within 30days, surgical site infection within 90days, or Clostridium difficile infection within 30days of urethroplasty. RESULTS: We identified 884 patients (81% antibiotic cohort, 19% nonantibiotic cohort) that met inclusion criteria. Age at time of urethroplasty, suprapubic tube presence, and pre-existing medical comorbidities were comparable between cohorts (Table 1A). There was no difference in 5-year rates and revision-free survival for endoscopic revision (11.5% vs 9.5%, relative risk (RR) 1.2, 95% CI [0.7, 2.0], recurrence-free survival (RFS) log-rank P = .6), re-do urethroplasty (12.9% vs 13.7%, RR 0.9, 95% CI [0.6, 1.5], RFS log-rank P = .7), or all-cause revision (19.8% vs 17.7%, RR 1.1, 95% CI [0.8, 1.6], P = .5) between groups. Postoperative rates of UTI, surgical site infection, and C difficile infection were similar between groups. CONCLUSION: In this large retrospective cohort study of patients undergoing urethroplasty with BMG, we observed no significant benefit from use of postoperative antibiotics on long-term revision rates or perioperative infectious complications.
