ABSTRACT
Retrograde urethrography (RGU) is a useful investigation to look for urethral injuries. It can result in various complications like anaphylaxis due to contrast material, urinary tract infection and intravasation or extravasation of contrast. In this case report, a rare complication of RGU was seen in the form of Fournier’s gangrene. This complication was probably due to extravasation of contrast material during the procedure which lead to reactionary changes of the penile skin and scrotum. Patient was managed aggressively and had a good recovery and is on regular follow up.
ABSTRACT
Background: Urethral strictures are relatively common in men with most patients acquiring the disease due to injury or infection. The present study was conducted to assess the accuracy of retrograde urethrography (RGU) in diagnosing urethral strictures in patients presenting with lower urinary tract symptoms.Methods: All male patients presenting with lower urinary tract symptoms and referred for retrograde urethrogram to the Department of Radiodiagnosis, Bharati Vidyapeeth Medical College and Hospital (Deemed to be University), Sangli from November 2018 till January 2019 were included. The parameters of RGU were compared with intra-operative findings as gold standard to calculate the operating characteristics of RGU.Results: The present study included 42 patients, mean age 54.9±11.2 years. Grade I urethral stricture was observed in 42.8% and 26% had grade II stricture. Bulbar stricture was the most common location. The common presenting complaints were increased frequency (50%) and dribbling micturition (40.4%). Approximately one tenth of all patients had a history of trauma. RGU was 100% sensitive and 66.7% specific in detecting strictures of less than 2 cm. Overall accuracy of RGU in detecting urethral strictures of less than 2 cm was 83.3%.Conclusions: RGU is a reliable means for establishing the diagnosis of a suspected urethral stricture and also provides accurate staging information with regard to stricture number, length, location, and coexistent urethral pathology.
ABSTRACT
Adverse reactions associated with parenteral use of contrast agents are widely recognized, but reactions to contrast agents following retrograde urethrography are much less common. A rare case of local allergic reaction to ionic contrast during retrograde urethrography in a 25-year-old male patient, who was treated conservatively, has been described.
ABSTRACT
PURPOSE: This study is designed to explore the role of retrograde urethrography as a predictor of recovery of urinary continence after radical retropubic prostatectomy. MATERIALS AND METHODS: A total of 40 patients who underwent radical retropubic prostatectomy from January 2005 to April 2007 were investigated. Among them one neurogenic bladder patient and one follow up loss patient were excluded. Voiding pattern and urinary incontinence were investigated with voiding diary monthly after Foley catheter removal. Recovery of urinary continence was defined as usage of less than 1 diaper per day. Pericatheter urethrography was conducted 2 weeks after operation. If definite bladder-urethral extravasation was not detected, an retrograde urethrography was performed immediately. 30 patients with sufficient length of urethra, regular margin of urethra and beaky appearance were defined as Group A, and 8 patients without above mentioned characteristics were marked as Group B. Differences between two groups were compared in terms of age, prostate volume, prostate specific antigen, urodynamic parameters, and duration of urinary incontinence. RESULTS: No significant differences were found in age, prostate volume, PSA between two groups. In group A, recovery rates of urinary continence were 70% (21 persons), 100% (30 persons) at 1,3 months after removal of catheter, respectively. In group B, rates of urinary continence recovery were 16.6% (1 person), 37.5% (3 persons), 75% (6 persons) at 1,3,4 months, respectively and 1 person regained continence at 7 months. CONCLUSION: A catheter free retrograde urethrography can be easily added after confirmation of bladder urethra anastomosis site healing. It gives us some valuable informations about external sphincter. The characteristics of retrograde urethrography can be used as a predictor of early recovery of postoperative incontinence.
