Experimental study of marginal wedge resection and its practical application in the surgical therapy of staghorn calculi.

A surgical procedure for staghorn calculi, which are inaccessible to conservative therapy, is described. It not only provides for complete elimination of the calculus but may also contribute to the prevention of recurrences. The technique of marginal wedge excision of the renal parenchyma, developed in animal studies, is described in detail and 11 surgical cases are reported. Removal of staghorn calculi was successful all throughout, and renal function remained unaffected by the intervention in all of the cases. Recurrences were confined to a single case. The procedure is safe, it involves no greater surgical strain than does marginal nephrotomy, but its short-term metaphylactic results seem more promising. Assessment of the long-term results awaits further observations.

Satellite peritoneal dialysis.

In 29 cases of chronic renal failure 1325 peritoneal dialyses were performed between January 1, 1976 and April 31, 1978. The technique of peritoneal dialysis, the general lines of supervision and follow-up, the results and shortcomings of the procedure are discussed. Peritoneal dialysis is regarded as an alternative to haemodialysis in chronic renal failure. On ground of the favourable observations, organization of satellite PD services on a large scale, parallel with the expansion of other services (haemodialysis, renal transplantation), is advocated.

Observations with the "Bi-flo" cannula (continuous, single-needle haemodialysis).

Observations with the double-lumen "Bi-flo" cannula in chronic intermittent haemodialysis are reported. On the evidence of urea and creatinine measurements, recirculation of blood corresponds to 7.9 and 6.1 per cent, respectively. In comparison with double-needle or single-needle dialysis, use of the double-lumen cannula does not affect the efficiency of dialysis to any notable degree. The advantages and shortcomings of the "Bi-flo" cannula with regard to the technique of dialysis are summed up.

Measurement of total-body 40potassium in patients with urate calculi.

Fifty-eight patients with urate calculi and 31 patients with other (non-urate) calculi were examined for total-body potassium by means of a total-body counter. The patients with urate calculosis were found to differ significantly in their total-body K from patients with other calculi as well as from normal subjects. The results indicate that total-body potassium deficiency is one of the factors causing urate calculosis.

[Surgical treatment of induration in penis plastica].

In the past 5 years the authors have removed the scar tissue in the case of the induration of the penis plastica of 43 patients by their special surgical method. Operation had to be repeated in the case of 5 patients. Twenty-five patients were cured, 15 improved and 3 remained unchanged after operation. The method, if applied with the necessary skill, is a recommendable method for the treatment of the induration of penis plastica. If, after operation the restoration of the function is not perfect, the application of supplementary conservative therapy is justified.

[Urologic diseases in the differential diagnosis of acute abdomen].

The urological diseases which alone or intercurrent with surgical and gynaecologic ailments cause most of the problems in the differential diagnosis of the acute abdomen are reviewed. The necessity of a cooperation between the urologist, surgeon and gynaecologist and the importance of intra-operative diagnosis are stressed.

A comparative study of three different citrate combinations of litholytic action.

Three different combinations--the Eisenberg solution, Uralyt-U and Magurlit--have been compared for their litholytic effect on urate calculi in a homogeneous patient material. Magurlit and Uralyt-U have been found superior to the Eisenberg solution, insofar as they are dispensed in a hygienic form easy to handle and require for the production of the litholytic pH levels a shorter time than does the Eisenberg solution. In opposition to other citrate combinations, Magurlit may be used with success even if the urate calculus contain an additional component, unless its distribution is unfavourable and its proportion exceeds 15 to 20%.

Operative management of variocele by high retroperitoneal ligation of the spermatic vein.

High retroperitoneal ligation of the internal spermatic vein has been performed in 30 cases of varicocele. Renospermatic reflux had been demonstrated by preoperative phlebography in every case. Retrograde pressure brought to bear on the spermatic vein from the renal vein has been ascertained by intraoperative measurements of the pressures in the internal spermatic vein. On the ground of the results, high ligation of the spermatic vein is regarded as suitable for the surgical management of varicocele in case of renospermatic reflux.

Factors influencing the prognosis of acute renal failure. (Analysis of 228 cases).

Two hundred and twenty-eight patients were treated for acute renal failure between October, 1964, and December 31, 1976. Complex antiuraemic therapy has been applied in 96, and haemodialysis or peritoneal dialysis in 132 cases. The overall mortality rate was 40.7%. The part played by age, primary process and possible complications of acute renal failure in the mortality figures is examined. From the analysis of clinical features, infections and septicaemia emerge as primary factors responsible for the high mortality. In conclusion the therapeutic measures which may minimize the hazard of inflammatory complications are summed up.

[A swallowed needle found in the kidney pelvis].

The case of a young female patient is discussed. The authors removed out of the renal hollow system of this patient a needle. The foreign body passed perorally into the renal pelvis after perforation of the duodenum. There the thicker end of the needle was encrusted; a pyelonephrosis, then a septic condition developed. After removal of the needle the kidney operated on showed a good function.

Bilateral testicular tumours.

After discussing the frequency of bilateral testicular tumours, attention is drawn to their rising incidence. In the 10 year period 1967 to 1976, three patients with bilateral testicular tumour were treated at the Department of Urology of the University Medical School of Pécs. Two had successively appearing bilateral seminoma and embryonal carcinoma, in the third patient simultaneously a malignant lymphoma appeared. As regards the question whether bilateral testicular tumours are two independent primary tumours or one is a metastastatic growth, presence of two primary tumours is assumed. The special features of therapy and prognosis are discussed.

[Clinical studies of Magurlit granulates].

The possibilities of dissolving by means of medication uric acid and uric acid-calcium oxalate calculi are discussed. The biochemical causes of uric acid lithogenesis was studied. Due to successful pharmacotherapy the number of operations has greatly diminished in recent years. On the basis of experience gained with various citrate mixtures the authors claim that Magurlit is the most advantageous litholytic drug. Due to its magnesium and vitamin B6 content it is also suitable for the dissolution of uric acid calculi containing calcium oxalate in diffuse distribution, i.e. for the prevention of the development of stones of this type.

[Marginal nephrectomy for the removal of coral calculi].

Efforts aimed at surgical solutions conserving the organs obtained importance also in renal surgery in recent years. This fact meant a milestone in the life of patients suffering from coral calculi, since it has been recommended to perform nephrectomy only in rare cases, and in the majority of cases young mothers were concerned. On the basis of the operation material comprising 12 cases--out of which some cases are described--the points of view of the marginal nephrectomy are discussed in detail. Among the modified techniques on the one hand the hairpin-shaped suture, on the other in the case of the local disease of the calyx system the marginal nephrectomy combined with wedge-shaped resection are explained, for the reduction of the danger of a recidivation of calculi an essential importance is ascribed to the last mentioned method.
