Magnetic resonance imaging with gadolinium DTPA assessment of bladder carcinoma and its response to treatment

Selection of appropriate managemenetof bladder carcinoma depends on accurate staging. Cystoscope and examination under anaesthesia are limited in their ability to assess deep tumour extension, extravesical spread and quite often radiotherapy bladder distortion by fibrosis and oedema obscure residual and recurrent tumour. MRI is accurate in staging of bladder carcinoma, the ability of Gd-DTPA-enhanced MRI it identify and define the extent of primary bladder carcinoma and to evaluate response to treatment in patients receiving and to detect residual and recurrent tumour after was also mentioned in this study

Sonography in evaluation of male anterior urethra

Ultrasonography offers advantages over conventional urethrography in terms of abnormalities detected, convenience of the study and lack of ionizing radiation. Our study favours sonography to be the examination of choice for both follow up of postoperative patients and for the evaluation of patients with new symptoms. The urologist may require a "road map" before surgery and for this purpose contrast urethra-gram may be more helpful

Evaluation of the sigma-rectum pouch as a urinary diversion after radical cystectomy in Egyptian patients

During 6 months period, a low pressure rectosigmoid reservoir for urine was created. This pouch [Mainz pouch II] obviates the need for colostomy, augmentation or extensive bowel surgery. Antimesenteric splitting of the rectosigmoid junction for 10-12 cm proximal and distal to this point and subsequent side to side anastomosis was performed. Urodynamic studies demonstrate that the detubularization is effective in rendering high pressure bowel contraction ineffective. The bowel was fixed at the promontory which lessens the risk of ureteral kinking and upper urinary tract dilatation. All the 18 patients that underwent this procedure were followed up for a period of 3-6 months. All patients except one were completely continent day and night. Only one female reported minimal soiling during night. The mean frequency was 5 times during day and 0-1 during night. The basal pressure within the sigma-rectum pouch at different filling volumes was 33 cm water. The low pressure improved continence, protected the upper urinary tract and even allowed dilated ureters to be implanted
