Ultrasound diagnosis of rupture of penile urethra in male buffalo calves

The present study was carried out in 6 male buffalo calves of 2–6 months of age which were suffered from complete urine retention with hot red swelling of the skin over the penile urethra. Ultrasonographic examination of the urethra (pre and post-scrotal) revealed disruption of the transitional epithelial lining in pre-scrotal urethra. The urethral lumen was observed as an irregular anechoic passage terminating near the preputial orifice. The anechoic shadow was more prominent towards ventral side of the penile urethra indicating more accumulation of urine toward this side. The dorsal side of penile urethra showed mere inflammatory changes. The infiltrated urine was visible as an anechoic pocket in the underlying connective tissue. There were hyperechoic multiple layers in between the anechoic pockets. The post-scrotal urethrotomy was performed to take the penis out and urethra was catheterised. Postoperatively, the calves were administered anti-inflammatory drugs alongwith antibiotics, B-complex, fluids and daily antiseptic, and dressing of the urethrotomy site was done. The catheter was placed in position for 2–3 weeks. After 2 weeks the swelling got subsided and urination became normal in 3 cases. In remaining 3 cases permanent opening for urination was made postoperatively. Out of 6 male buffalo calves, only 4 could survive.
