A 50-year-old man presented to us with complaints of dysuria and narrowing of urinary stream after multiple attempts at catheterisation due to acute urinary retention following hernioplasty under spinal anaesthesia at some other hospital. Patient did not reveal the history of passage of a hard instrument like introducer via his urethra nor was it mentioned in the discharge notes of the patient. Patient had history of urethral stricture disease for which he had underwent endoscopic dilatation about 5 years back, although patient was not symptomatic for urethral stricture disease at the time of surgery. The urine analysis and routine blood investigations of the patient were unremarkable. We performed a retrograde urethrography of the patient, which showed the presence of two wide calibre passages in the region of prostatic urethra both opening at the level of verumontanum (figure 1). This radiological picture made it difficult to discern the true urethral passage from the false one, so urethroscopy of the patient was contemplated. On urethroscopy, two openings were visible in the bulbar urethra (figure 2). We gently probed the lower urethral mucosal bud with a guidewire and negotiated it into urinary bladder with ease. Gentle urethroscopy along guidewire revealed it to be the true urethral passage opening into the bladder while inspection of the other parallel passage revealed it to be a blind ending false passage. With the aid of an optical urethrotome, we incised the floor of the false passage guided by the guidewire along the urethra and negotiated a 16 Fr Foley catheter over guidewire into the urinary bladder. The catheter was kept in situ for 7 days. Patient was voiding well after 2 months of follow-up without any complaints of dysuria or thinning of urinary stream.
Catheterisation is a common procedure done after major surgeries at many centres in the world. Although being a common procedure, complications like trauma to urethra, haematuria, infection and acute urinary retention due to inflation of balloon of Foley catheter in urethra are frequently encountered. In our case, the patient developed a false passage contiguous to the urethra due to repeated attempts at catheterisation done for acute urinary retention after undergoing hernioplasty for right inguinal hernia.1 2 The creation of a false passage and stricture urethra are the most common complications of attempted catheterisation per urethra. These cases require a careful and complete endoscopy of the urethra to ward off mistaking a false passage for the true urethral lumen.3
Patients with a history of urethral stricture should be catheterised gently and preferably over a guidewire.
In wide calibre false passages alongside the urethra, it may be difficult to discern the true urethral lumen on retrograde urethrography only.
Urethroscopy serves as an important adjunct to retrograde urethroscopy in ruling out a large calibre false passage running contiguous to the urethra.
