Superficial bladder tumors (stage pTa, grades 1 and 2): the importance of recurrence pattern following initial resection.

We treated 414 new patients with stage pTa, grades 1 and 2 bladder tumors by transurethral resection between 1970 and 1982. All of the patients with grade 3 or previous upper tract tumors, or who had been treated at some stage with intravesical chemotherapy were excluded. Followup for 5 or more years was available in 188 of the patients. There was a low increase in T stage (6 per cent). Of the patients followed for 5 or more years 46 per cent remained free of tumor. Only 16 per cent of the patients had multiple tumors at presentation and 20 per cent had tumors of 10 gm. or more. These factors were associated with a worse prognosis. Patients free of tumor at 3 months had an 80 per cent chance of having no further recurrences and this rate remained the same up to 2 years from the start of the disease. Patients with a recurrence at 3 months were much less likely to remain free of tumor, and had a higher chance of recurrence at every future visit.

Bladder neck contracture following prostatectomy.

In an 11-year period, 49 patients developed bladder neck contracture after prostatectomy--an incidence of 0.86%. This complication was found to be more common after resection of small fibrous hyperplastic prostates. The best results for treatment of the contracture were obtained after bladder neck incision, which gave a 9% incidence of recurrence; after transurethral resection of the bladder neck contracture the recurrence rate was 46%, and after bladder neck dilatation it rose to 100%.

A 15-year follow-up of 406 consecutive spinal cord injuries.

A follow-up of 406 traumatic spinal cord injuries admitted from 1967 to 1982 is presented. Forty patients died, only two (5% of deaths and 0.5% of the series) from renal complications. Twenty-seven died from pulmonary or cardiovascular causes, complete and cervical lesions being the most significant factors in mortality. Early and continued active urological treatment aimed at the provision of low pressure bladder drainage to protect the upper tract. The management and results are critically discussed.

Tuberculous stricture of ureter.

Tuberculous stricture of the ureter is not uncommon in centers which treat large numbers of patients with urinary tuberculosis. Ninety-seven such strictures were seen in 92 patients over a twenty-five-year period. All patients were treated with appropriate antituberculous chemotherapy. Transurethral dilatation of the ureteral stricture was done on 80 ureters. Dilatation was successful in 51 ureters (64%) and failed to relieve the strictures in 29. Technical difficulties prevented dilatation of 17 ureters. We believe that transurethral dilatation should be attempted on all tuberculous ureteral strictures and that other procedures should be employed only if dilatation fails.

Ureterovaginal fistula: a report of 12 cases and review of the literature.

Ureterovaginal fistula is an uncommon complication of pelvic operations, seen most often after Wertheim's hysterectomy. We report 12 cases of ureterovaginal fistulas seen during a 20-year period, all of which followed operations for benign gynecologic conditions. Most patients had no urinary symptoms until the sudden onset of incontinence 1 to 4 weeks postoperatively. Diagnosis was established readily by a combination of excretory urography, cystography, cystoscopy, retrograde pyeloureterography and dye studies. In our series only 1 patient was treated by primary nephrectomy, while 11 underwent ureteroneocystostomy: 2 with a Boari flap and 9 by a direct method. Reconstruction failed in 2 patients, 1 of whom required a secondary nephrectomy.

The treatment of ureteric stones: report on 1120 patients.

A consecutive series of 1120 patients with ureteric stones is presented. Conservative and surgical treatment is discussed and the results of ureteric catheterisation, dilatation, transurethral manipulation and extraction, ureteric meatotomy and ureterolithotomy are presented.

Primary nonfunctioning carcinoma of adrenal cortex.

Two cases of nonfunctioning adrenocortical carcinomas are presented. The clinical features, operative findings, and histopathologic appearances are discussed. It is believed that these tumors are difficult to diagnose because of their vague presentation. Intravenous urography with nephrotomography is the most valuable method of detecting these tumors, and surgery remains the best treatment.

Epodyl in management of noninvasive vesical neoplasms.

A prospective study to assess the effects of triethylene glycol diglyceridyl ether (Epodyl) in the management of superficial noninvasive vesical neoplasm (T1) is presented. Apart from a few local side effects, the response of the tumor to Epodyl was very good as assessed up to three years. Further long-term studies are being done.

Early and late management of the neuropathic bladder in spinal cord injury patients.

Early and late management of neuropathic bladders in 562 consecutive patients with spinal cord injuries is described. Indications for an operation to relieve outlet obstruction by transurethral resection and external sphincterotomy are outlined, and the management of urinary infection and incontinence is discussed. Approximately 30 per cent of all spinal cord injury patients had outlet obstruction for which either external sphincterotomy, transurethral resection or both procedures were necessary. Operations appeared to be required more frequently in patients with complete and thoracic lesions, and more than 1 operation may be necessary to achieve satisfactory bladder emptying.

Transurethral removal of bladder stone: the place of litholapaxy.

The surgical management of 652 cases of bladder stone, with particular reference to the value of litholapaxy, is discussed. The majority of cases can be treated by closed methods--litholapaxy and transurethral removal. Those cases treated by closed methods have a reduced postoperative complication and morbidity rate, a shorter operating time, and a reduced period of hospitalisation. Provided the necessary skill is acquired, it is concluded that litholapaxy is a safe and efficient method of dealing with bladder stones.

Hydrostatic overdistension for contracted tuberculous bladder. A review of 61 cases.

When a contracted tuberculous bladder is not improved on anti-tuberculosis drug treatment the bladder capacity can be increase by hydrostatic overdistension, done either cystoscopically if reflux is present, or by using a balloon catheter. Of 61 cases so treated, 40 showed marked improvement and 24 of these needed only one overdistension, and the rest required more than one treatment. Nine cases showed no improvement but no further deterioration and 12 cases had continued deterioration.

An assessment of surgical treatment of vesical outlet obstruction in spinal cord injury: a review of 471 cases.

An assessment of 139 cases of outlet obstruction following spinal cord injury, in a consecutive series of 471 patients, is presented. The figures in relation to the level and extent of the spinal lesion and the type of operation (transurethral resection and external sphincterotomy), are reviewed. The incidence of repeat operation is recorded and assessed. It is concluded that transurethral resection and external sphincterotomy, either alone or combined, will relieve outlet obstruction in most cases of neuropathic bladder following spinal cord injury.
