The current study aimed to evaluate the effectiveness of fascia lata for grafting of the urinary bladder. Clinical, ultrasonographic and radiographic evaluations were performed. The study was carried out on ten healthy mongrel dogs of both sexes. They were divided into two equal groups. The animals in the control group were subjected to cystectomies, followed by suturing of the remaining wall using an inverting suture technique. The dogs in the Fascia lata group were subjected to partial cystectomies followed by grafting using fascia lata which was harvested from the thigh region. The graft was sutured to the bladder using the inverting suture pattern. The results revealed that the animals in both groups were healthy throughout the experiment except two animals in the control group showed urinary incontinence at the early post-operative period. One animal in the fascia lata group showed incontinence and another one displayed arching of the back in the first three days post-operation. The ultrasonographic and radiographic evaluation revealed a well-contoured bladder without any leakage. The bladder volume was significantly decreased in the control group post-operatively compared to the pre-operative manual measurement. However, there was no significant variation in the bladder volume pre- and post-grafting in the fascia lata group when measured manually and radiographically. Ultrasound is considered an unreliable method for measuring bladder volume. The results showed that fascia lata is an easily harvested tissue used for grafting the urinary bladder. It causes no complications (leakage, stone formation), and it keeps bladder capacity within normal or close to normal.
