[Repeated internal urethrotomy in male urethral stricture].

The results of further treatment of 40 patients with recurrence of urethral stricture following internal urethrotomy are assessed. Repeat internal urethrotomy was often successful even in cases presenting with extensive stricture, multiple stenoses or stenosis in an unfavourable site. Altogether 47% of the patients remained recurrence-free after the second attempt at internal urethrotomy. Open surgery was necessary in 3 patients. In old or unfit patients who could not be subjected to open surgery internal urethrotomy was performed up to 5 or even 6 times. This operation is often preferred by patients to conservative forms of treatment such as bougienage or an indwelling catheter. It is tolerated well, even on a repeated basis and the complication rate is low.

[Success of internal urethrotomy as the 1st operation in male urethral stricture].

A follow-up examination was possible on 179 out of 226 patients operated on for urethrostenosis using sight urethrotomy according to Sachse. The results are classification according to the observation period, ranging from 3 months to 3 years. The most important criteria of a successful operation were lack of discomfort and a rise in uroflow to over 10 ml. Relapses occur more frequently than average in patients who had recidive infections of the urinary tract before the operation. Where the operation was successful the urinary tract infection almost always subsided. Recidive strictures occurred frequently in patients over 70 years. However, internal urethrotomy is often the only suitable method of operation at that age. Long prior bouginage makes prognosis worse. In terms of aetiology, iatrogenic stenoses give the worst results, bulbar ring stenoses, the best. In cases of long stenoses, particularly in the penile part of the urethra, the results of the operation are clearly worse than average, so that another method of operation should be considered, especially if the patients are young.

[Treatment of Wilms' tumor (author's transl)].

Uniform treatment based on the therapeutic approach of the 1st and 2nd US National Wilms' Tumor Study was decided on in March 1976 by paediatricians, surgeons, urologists and radiotherapists in Austria. Wilms' tumour was diagnosed in 34 children between 1 january 1976 an 29 february 1980 (stage I: n = 11, stage II: n = 8, stage III: n = 8, stage IV: n = 7). Parents of two children refused treatments; both children have since died of metastases. Of the remaining 32 children 29 (90.6%) are alive, 10 for more than 4, 15 for more than 3 and 19 for more than 2 years after diagnosis. 21 children are without need of treatment. Three children have died, one due to postoperative complications, one due to haemorrhagic chickenpox, but free of tumour, and one after insufficient treatment. Two of the five children with a recurrence between 2 1/4 to 15 months after diagnosis had been treated inadequately in the initial phase. The tumour free survival rate in 74.2%. Two children with early occurring or recurrent lung metastases have survived for 53 1/2 and 54 months up to now.

[Long-term observations after adrenal surgery].

Long-term observations after adrenal surgery show different results according to indications for operations. The longest period of observation shows 8 patients with adrenal hyperplasia. In 3 of 4 bilaterally adrenalectomised patients no satisfactory results were obtained despite substitution treatment; 4 one-side adrenalectomised patients are in good condition. Operative results of 7 patients with benign phaeochromocytoma are satisfactory. Two patients with malignant phaeochromocytoma developed a local recidive and distant metastases. Carcinoma of the adrenal gland, if not hormonally active, were not diagnosed in early stage, 3 patients died from metastases within 3 years. A 2-years-old girl, who was operated on with hormonally active carcinoma, is in good condition 21 years later.

[Autologous ureter transplantation. Results of animal experiments].

Autologous transplantation of the ureter in the whole lengths was carried out successfully. After unilateral nephrectomy the ureter was cut from the bladder, denudated and wrapped in the omentum majus. 4 weeks after that operation revascularisation of the ureter was pronounced so that the ureter could be used for reanastomosis with the renal pelvis and the bladder on the contralateral side. One dog lived with the transplanted ureter for one year and then died during birth of 5 puppies. One dog is living now since two years and is healthy.

[Renal vein thrombosis in childhood (author's transl].

The disease of renal vein thrombosis in children is presented on the basis of own observations and literature, whereby frequency, etiologic factors, and the age of manifestation are mentioned. The clinical symptoms are dependent on the localisation and the intensity of the thrombotic changes in the renal vein system which can be proven by the histological findings. The main symptoms of a renal vein thrombosis are hematuria, palpable enlargement of the kidney and pathological findings in the intravenous urography. Occasionally symptoms of an obliteration of the vena cava can appear, and in the complex disease picture a consumption coagulopathy can occur. The possibilities in therapy are pointed out, and above all, the question of the optimal time for a nephrectomy the most important point is discussed. In a self-observed newborn baby with unilateral renal vein thrombosis a relatively early nephrectomy-on the fifth day of life-a complete recovery could be achieved. The different opinions of thrombectomy are presented.

[Acute urological management of children with myelomeningocele (author's transl)].

A summary on the possibilities of urological investigations of patients with myelomeningocele during the first days of life shows, that the i.v. Pyelography, the mictiurationcystourethrogram and the cystosphincteromanography are suitable techniques for early detection of obstructive uropathy. From these investigations the indecations for proper operative techniques can be derived.
