Results of the surgical treatment of congenital hydronephrosis caused by subpelvic obstruction.

The results of surgical treatment for obstruction at the pyeloureteral junction in 282 patients, both children and adults, are presented. Most of the patients were treated by the Anderson-Hynes method, without nephrostomy. Good results were achieved in 71.2%, satisfactory ones in 20.4% of the cases. The rest of the patients underwent further surgery. The causes of late and early postoperative complications are analysed. A good result depends upon the adequate choice of operation and the correct technique of its performance.

Analysis of urinary tract infections in patients undergoing prostatectomy.

Analysis is presented of 260 patients on whom in the years 1974--1976 an operation for adenoma removal was performed. 115 patients (44.2%) had a permanently placed catheter or were repeatedly catheterized before operation, and 145 (55.8%) were able to urinate without any need for catheterization. In the group of preoperatively catheterized patients infection of the urinary system was demonstrated in 84 cases, which amounts to 75%. Among patients not catheterized before operation, infection already existed in 29 cases (20%). Operation by Millin's method was carried out in 181 patients; non-infected urine was postoperatively found in 40 cases, which amounts to 22.3%. 79 patients were operated on by the transvesical method; in this group non-infected urine was found in four cases, i.e. 5.1%. Calculated x2 indicated a significant connection between the investigated items, consisting in a much more frequent occurrence of urinary system infection in patients operated on by the transvesical method. The duration of catheter reposition in the urinary bladder after prostatectomy considerably influences the number of postoperative infections of the urinary system.

Polyps of the urethra in children.

The authors present two cases of polyps of the urethra occurring exclusively in boys: one in a 12-month-old infant, the other in a 15-year-old boy. In both patients the polyp caused dysuria or urinary retention. Diagnosis was based on mictional cystography. This examination usually gives a picture of a filling defect spotted in the area of the bladder neck. During miction the defect may move deeper into the urethra. An endoscopic examination may be also helpful. The authors believe that treatment should consist in total excision of the polyp together with its base through the open urinary bladder. Polyps of the urethra have to be differentiated from a valve of the posterior urethra or a shadowless calculus. After total excision of the polyp prognosis is good.

Tumours of the urinary bladder accidentally diagnosed during prostatectomy.

By analysing 1472 prostatectomies, the authors have stated a coexistence of tumour of the bladder in 31 cases (2.11%). In 11 patients (0.75%) the tumours were accidentally diagnosed, as late as during the operation itself. Eight patients were operated transvesically. The tumour was diagnosed immediately after opening the bladder. The tumour was removed first and then the adenoma. Three patients were operated on according to Millin's method, their tumours having been detected only after enucleation of adenoma of the prostate. In five cases cancer of the bladder was diagnosed and in six papillary tumour of the bladder was found. The bladder cancers were treated by partial excision of the bladder or by deep electrocoagulation. The authors maintain that the small percentage of accidentally diagnosed tumours is no indication for a routine performance of cystoscopy in every case of adenoma of the prostate before intended prostatectomy.
