Calvo CI, Rourke KF. Routine Imaging After Bulbar Urethral Reconstruction Does Not Impact Surgical Outcomes and May Not Be Necessary. Urology 2024; 186:41-47. [PMID: 38417467 DOI: 10.1016/j.urology.2024.02.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/02/2024] [Accepted: 02/21/2024] [Indexed: 03/01/2024]
Abstract
OBJECTIVE To assess whether omitting routine post-operative imaging adversely impacts clinical outcomes after bulbar urethroplasty. Contrast imaging is commonly performed prior to catheter removal after urethroplasty but the clinical need for this is unclear. METHODS This was a matched, case-control analysis comparing patients undergoing routine voiding cystourethrogram (VCUG) prior to catheter removal after bulbar urethroplasty to patients without imaging. Patients were matched with respect to age, stricture etiology, length, and urethroplasty technique. Follow-up consisted of clinical assessment 3 weeks post-operatively for VCUG/catheter removal, cystoscopy at 3-4 months with clinical assessment annually. Outcome measures were 90-day complications (Clavien ≥2) and stricture recurrence (failure to pass a 16-Fr flexible cystoscope on follow-up). Chi-square and Kaplan-Meier analysis were conducted where appropriate. RESULTS Hundred patients undergoing bulbar urethroplasty with VCUG prior to catheter removal were compared to 100 matched case controls without imaging. Groups did not differ with respect to failed endoscopic treatment (P = .82), prior urethroplasty (P = .09), comorbidities (P = .54), smoking (P = .42), or pre-operative bacteriuria (P = 1.00). The incidence of extravasation in the VCUG group was 2%. Overall 90-day complications were 9.5% and 15 patients developed recurrence with a median follow-up of 174 months. On chi-square analysis, 90-day complications did not differ between patients undergoing VCUG and those without (12% vs 7.0%; P = .34). On log-rank analysis, stricture recurrence did not differ between groups (P = .44). CONCLUSION Routine imaging with VCUG after bulbar urethroplasty does not influence the risk of post-operative complications or stricture recurrence. Surgeons should consider avoiding this potentially unnecessary examination in routine clinical practice.

Abstract
Optimum radiological assessment of the male urethra requires knowledge of the normal urethral anatomy and ideal imaging techniques based on the specific clinical scenario. Retrograde urethrography is the workhorse examination for male urethral imaging, usually utilized as the initial, and often solitary, modality of choice not only in the setting of trauma, but also in the pre- and post-operative evaluation of urethral strictures. There is, however, growing interest in utilization of ultrasound and magnetic resonance for evaluation of the male urethra owing to lack of ionizing radiation and improved delineation of the adjacent tissue. We review the various modalities utilized for imaging of the male urethra for a variety of known or suspected disorders, and provide an update on current treatments of urethral strictures. Additionally, we detail the key information needed by urologists to guide management of urethral strictures. We conclude with a brief discussion of neophallus urethral diseases following female-to-male sexual confirmation surgery.

POIROT trial: post-operative imaging after urethroplasty with peri-catheter retrograde urethrography or trial of voiding with voiding cysto-urethrography. World J Urol 2022; 40:1195-1201. [PMID: 35098358 DOI: 10.1007/s00345-021-03915-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 12/16/2021] [Indexed: 12/13/2022] Open
Abstract
PURPOSE This study directly compares peri-catheter retrograde urethrography (pcRUG) and voiding cysto-urethrography (VCUG) as early postoperative imaging after urethroplasty and aims to assess whether pcRUG is superior at avoiding catheter reinsertion. METHODS This is a single-center, prospective, interventional study comparing pcRUG and VCUG after urethroplasty in a within-patient fashion. All participants were first evaluated with pcRUG and subsequently with VCUG, unless pcRUG revealed significant contrast extravasation warranting further catheter stay. The primary end-point was to assess whether pcRUG is superior at avoiding catheter reinsertion compared with VCUG. Secondary end-points included the amount of significant contrast extravasations missed on pcRUG and the differences in radiation exposure. RESULTS 80 patients were included in this study. Median (IQR) interval between surgery and first postoperative imaging was 16 (9-16) days. In 14/80 (18%) patients, the pcRUG showed significant contrast extravasation and catheter reinsertion was avoided, while this percentage is 0 by default for VCUG (p < 0.001). In the other 66/80 (82%) patients, a VCUG was performed and 1/66 (1.5%) of these was considered as significant contrast extravasation. Notably, 9/66 (14%) of these patients could not void during the investigation. Median (IQR) dose of radiation exposure during pcRUG and VCUG was, respectively, 120 (84-161) mGy/cm2 and 241 (169-334) mGy/cm2 (p < 0.001). CONCLUSIONS After urethroplasty, pcRUG is a valuable alternative for VCUG as early postoperative imaging. It has a comparable diagnostic yield, averts the risk of having to reinsert the catheter, avoids the problem of patients being unable to void during the examination and requires significantly less radiation.

Abstract
CONTEXT Urethral stricture management guidelines are an important tool for guiding evidence-based clinical practice. OBJECTIVE To present a summary of the 2021 European Association of Urology (EAU) guidelines on diagnosis, classification, perioperative management, and follow-up of male urethral stricture disease. EVIDENCE ACQUISITION The panel performed a literature review on the topics covering a time frame between 2008 and 2018, and using predefined inclusion and exclusion criteria for the literature. Key papers beyond this time period could be included if panel consensus was reached. A strength rating for each recommendation was added based on a review of the available literature after panel discussion. EVIDENCE SYNTHESIS Routine diagnostic evaluation encompasses history, patient-reported outcome measures, examination, uroflowmetry, postvoid residual measurement, endoscopy, and urethrography. Ancillary techniques that provide a three-dimensional assessment and may demonstrate associated abnormalities include sonourethrography and magnetic resonance urethrogram, although these are not utilised routinely. The classification of strictures should include stricture location and calibre. Urethral rest after urethral manipulations is advised prior to offering urethroplasty. An assessment for urinary extravasation after urethroplasty is beneficial before catheter removal. The optimal time of catheterisation after urethrotomy is <72 h, but is unclear following urethroplasty and depends on various factors. Patients undergoing urethroplasty should be followed up for at least 1 yr. Objective and subjective outcomes should be assessed after urethral surgeries, including patient satisfaction and sexual function. CONCLUSIONS Accurate diagnosis and categorisation is important in determining management. Adequate perioperative care and follow-up is essential for achieving successful outcomes. The EAU guidelines provide relevant evidence-based recommendations to optimise patient work-up and follow-up. PATIENT SUMMARY Urethral strictures have to be assessed adequately before planning treatment. Before surgery, urethral rest and infection prevention are advised. After urethral surgery, x-ray dye tests are advised before removing catheters to ensure that healing has occurred. Routine follow-up is required, including patient-reported outcomes. These guidelines aim to guide doctors in the diagnosis, care, and follow-up of patients with urethral stricture.

Urethrogram: Does Postoperative Contrast Extravasation Portend Stricture Recurrence? Urology 2020; 145:262-268.

Abstract
OBJECTIVE To demonstrate our hypothesis that the presence of extravasation on postoperative urethrogram is inconsequential for disease recurrence in urethroplasty postoperative follow-up. MATERIALS AND METHODS We utilized the Trauma and Urologic Reconstructive Network of Surgeons database to assess 1691 patients who underwent urethroplasty and post-operative urethrogram. Anatomic and functional recurrence were defined as <17 Fr stricture documented at 12-month cystoscopy and need for a secondary procedure during 1 year of follow-up, respectively. Our primary outcomes were the sensitivity and positive predictive value of post-operative urethrogram for predicting anatomic and functional recurrence of urethral stricture disease. RESULTS Among 1101 patients with cystoscopy follow-up, 54 (4.9%) had extravasation on initial postoperative urethrogram. Among those 54, 74.1% developed an anatomic recurrence vs 13% without extravasation (P <.001). Similarly, functional recurrence was 9.3% with extravasation vs 3.2 % without extravasation (P = .04). Patients with extravasation more often reported a postoperative urinary tract infection (12.9% vs 2.7%; P <.01) or wound infection (7.4% vs 2.6%; P = .04). Sensitivity of postoperative urethrogram in predicting any recurrence was 27.3%, specificity 98.7%, positive predictive value 77.8%, and negative predictive value 89.3%. Fourty-five of 54 patients with extravasation had a recurrence of some kind, equating to a 22.2% urethroplasty success rate at 1 year. CONCLUSION Postoperative urethrogram has a high specificity but low sensitivity for anatomic and functional recurrence during short term follow-up. The positive predictive value of urinary extravasation is high: patients with extravasation incur a high risk of anatomic recurrence within 1 year and such patients may warrant increased monitoring.

Abstract
Urethral strictures are a relatively common affliction of men with the anterior urethra being most frequently affected. Anterior urethral strictures (AUS) typically present with obstructive voiding symptoms and appropriate management is often based on findings at cystourethroscopy and retrograde urethrography (RUG). In particular, determining the number, length, severity and location of urethral strictures is of pivotal importance. The accurate reporting of findings at RUG is dependent on a thorough knowledge of the urethral anatomy as well as recognizing periurethral structures that may opacify during the procedure. Obtaining a diagnostic, high-quality RUG study requires adherence to proper fluoroscopic technique as well as recognizing when to adjust or modify the technique to address pitfalls that may be encountered during the procedure. AUS may be treated by a variety of procedures including urinary diversion, transurethral procedures such as urethral dilation and internal urethrotomy and open surgical repair techniques termed urethroplasty. Some authors have recommended urethroplasty as first-line treatment given the high rate of stricture recurrence with other treatment options. Buccal mucosal grafts are a mainstay of modern urethroplasty. Familiarity with the commonly performed urethroplasty procedures allows radiologists to accurately assess the post-operative urethra thus guiding the management of these patients.

Abstract
Purpose: Obliterative urethral stenosis is a type of urethral lesion that compromises the whole corpus spongiosum's circumference. We present our experience in resolving complex long segment urethral obliteration in a single procedure using a combination of dorsal onlay oral mucosa graft (OMG) and ventral fasciocutaneous penile skin flap. Materials and methods: A prospectively maintained database was reviewed, which included data of men presenting long, obliterative strictures. Patients were excluded if they were lost to follow-up before one year. Failure was defined as need for further urethral instrumentation. The surgical technique used consisted on the fixation of OMG to the tunica albuginea of the corpus cavernosum, thus creating a new urethral plate. Penile or foreskin flaps were employed to complete the ventral aspect. Postoperative follow-up was done with a voiding cystourethrography at week 3. Results: A total of 21 patients were included with a median age of 49 years. Mean follow-up was 25 months. Failure was found for 3 patients (2 of them needing dilations and only one required a new urethral reconstruction). Conclusion: Single stage combination of dorsal OMG with ventral fasciocutaneous penile flap showed good results for selected patients affected with obliterative urethral stenosis.

Abstract
OBJECTIVE The aim of this article is to describe the indications and proper technique for RUG and MRI, their respective image findings in various disease states, and the common surgical techniques and imaging strategies employed for stricture correction. RESULTS Because of its length and passage through numerous anatomic structures, the adult male urethra can undergo a wide array of acquired maladies, including traumatic injury, infection, and neoplasm. For the urologist, imaging plays a crucial role in the diagnosis of these conditions, as well as complications such as stricture and fistula formation. While retrograde urethrography (RUG) and voiding cystourethrography (VCUG) have traditionally been the cornerstone of urethral imaging, MRI has become a useful adjunct particularly for the staging of suspected urethral neoplasm, visualization of complex posterior urethral fistulas, and problem solving for indeterminate findings at RUG. CONCLUSIONS Familiarity with common urethral pathology, as well as its appearance on conventional urethrography and MRI, is crucial for the radiologist in order to guide the treating urologist in patient management.
