Combined occurrence of prostate carcinoma and malacoplakia.

This is a case of a 56-year-old male patient suffering from a combination of prostate carcinoma and malacoplakia. A 56-year-old male patient was admitted in our Department because ischuria due to the enlargement of the prostate. Perineal needle biopsy was done resulting carcinoma of prostate.

Giant adrenal myelolipoma.

Authors present a case of giant adrenal myelolipoma, where the tumor was hormonally inactive but caused abdominal and flank pain. The huge tumor, a 20x18x10 cm mass, was surgically removed. The ipsilateral kidney was preserved.

[Urinary bladder and paraurethral endometriosis].

Authors report a case of bladder and a case of paraurethral endometriosis. The mode of sanitation was by means of TUR and surgery, respectively. Based on the available literary data, the assumptions related to development of the disease; its pathology, symptoms and treatment are discussed in brief.

Heteromorphic grade of renal cell cancer.

The present study demonstrates by means of histopathologic analysis that most of the renal adenocarcinomas are microscopically heterogeneous--named by authors as heteromorphic. This heteromorphism means the mixture of different cell types, histological patterns and fields of tumor with different nuclear atypia. 300 surgical specimens of renal cell cancer (RCC) were reclassified retrospectively.

Isolated urethral amyloidosis (case report).

A case of urethral amyloidosis is presented in a 31-year-old male patient. Through this case, authors draw attention to the recommended forms of examination in the event of this illness being suspected, and also discuss problems in differential diagnosis. A reviewed the relevant data in the literature is also provided.

Metabolic consequences of orthotopic ileal neobladder.

Purpose: Orthotopic ileal bladder substitution is a well accepted form of urinary diversion providing high quality of life. However, potential metabolic consequences remain a serious problem. These complications are discussed in the present article.

Comparison of morbidity of lumbar flank approach and transperitoneal approach for radical nephrectomy.

Purpose: This is a retrospective study comparing the clinical data and morbidity of transperitoneal radical nephrectomy (TRN) and simple nephrectomy.

Material And Methods: From 1st January, 1989 to 1st January, 1996 a total of 90 simple nephrectomies and from 1st January, 1996 to 1st August, 1999 a number of 85 TRN were performed at the Department of Urology of the Saint Stephen Hospital. The analysis of clinical data included operative time, length of analgesics, postoperative hospital stay and blood loss, as well as morbidity.

Eosinophilic cystitis.

Authors report on two rare cases of eosinophilic cystitis, giving a review of the etiologic assumptions and pathogenetic, pathologic aspects of the disease, based on the available literary data. The course of the disease can be either acute or subacute, and is most often chronic. Relapse and progression can interchange in irregular manner, attention is therefore called to the importance of follow-ups.

Anatomic variations in patients operated for bladder substitution.

Authors review the anatomic variations observed throughout orthotopic ileal neobladder formation in 38 cases following radical cystectomy. A part of the variations was necessitated because of deviation from the classic Hautmann-type surgical technique: in 6 cases the site of ileal resection was modified due to abnormal mesenterial art. course, on 2 occasions Meckel diverticules were detected while cutting the ileal neobladder, in 13 cases the laterally adhered sigma bladder necessitated the left-sided ureter to be pulled through beneath the mesosigma for the purpose of making sure the ureter--ileal neobladder anastomosis became free of any tension, while on 1 occasion the left ureteral preparations went with some injury.

A case of a calcified renal cyst.

Authors review a case of a calcified renal cyst. The literary data at hand give evidence that the spreading processes in the kidney can be benign or malignant according to their form of calcification and their localisation. Despite the modern diagnostic techniques, it is not easy to set up the diagnosis or to avoid the need for surgery, as was the case in the present report.

Retroperitoneal malignant fibrous histiocytoma.

Authors review the case history and follow-up of a rare malignant fibrous histiocytoma patient, based on the relevant literary data. The tumour filled the retroperitoneum on the right side, in front of the right kidney. Intravenous urography and computer tomography revealed a 10 x 15 cm sized mass, suspect of being a kidney tumour.

Prognostic index of renal carcinomas.

Authors analysed the survival of 126 patients operated for kidney carcinomas. The data on anamnesis, laboratory results and TNM histological classification were compared with the results on "relative survival" and correlation analysis was performed. Based on these, the 12 most important criteria (with the highest correlation coefficient) were emphasized and regression equation was formed based on the TSP (Time Series Processing) Version 4 (Hall).

Retroperitoneal malignant fibrous histiocytoma.

Authors review the case history and follow-up a rare malignant fibrous histiocytoma patient, based on the relevant literary data. The tumor filled the retroperitoneum on the right side, in front of the right kidney. Intravenous urography and computer tomography revealed a 10 x 15 cm sized mass, suspect of being a kidney tumor.

Schistosomiasis of the urinary bladder.

Authors review a case of urinary schistosomiasis, where the process caused left-sided urinary obstruction. Because of the suspicion of a tumor transurethral resection was performed, whereafter the ureter passage became unhindered. Diagnosis became clear upon the histological examination of the resected tissue.

Factors affecting prognosis of renal cell carcinomas.

Author analyzed the survival of 126 patients operated on because of kidney carcinomas. The data on anamnesis, laboratory results and TNM histological classification were compared with the results on "relative survival" and correlation analysis was performed. Based on these, the 12 most important criteria (with the highest correlation coefficient) were emphasized and regression equation was formed based on the TSP--Time Series Processing--Version 4 (Hall).

Experiences on 25 cases of radical cystectomy.

Authors review their early experiences and the oncopathological relations in respect to 25 cases of radical cystectomy involving orthotopic bladder substitution. The difficulties of diagnostics and indication are discussed. Attention is drawn to the fact that pathological "staging", "grading" are not entirely exact and reliable, though surgical indication is positioned on these.

Experiences of 25 orthotopic ileal neobladders.

Authors report on their results obtained from orthotopic ileal neobladders following 25 cases of radical cystectomy. Analysis is given of the possible complications, their prevention, as well as of surgical techniques. It is determined that orthotopic ileal neobladder is one of the best bladder substitution methods, giving the patient a chance for a high quality of life.

[Schistosomiasis of the bladder].

Authors review a case of urinary schistosomiasis, where the process caused left sided urinary obstruction. Because of the suspicion of a tumor transurethral resections was performed, where after the ureter passage became unhindered. Diagnosis became clear upon the histological examination of the resected tissue.

Kidney oncocytoma.

Authors review the case history of three patients with kidney tumours which had been surgically removed. In two of the cases radical nephrectomy while in one, organ-preserving surgery was performed. In all the cases histology revealed benign kidney tumours--oncocytomas.

Bilateral ureteric replacement with ileum.

In connection with a report of a case, authors discuss in outline the possibilities of ureter replacement. If both the ureters are injured, they can be substituted with one single segment of the intestine, as it happened in their case. Authors raise the idea that a longer segment of the intestine used for substitution provides sufficient capacity and isoperistaltic function, and this may protect from the negative effects of possible vesicoileal reflux.

Organ-preserving surgery of renal cell carcinoma: report of four cases.

Authors removed the renal tumour of four patients by means of resection in an organ-preserving manner. Of the four patients, one had bilateral carcinoma. The right-sided carcinoma of this patient was removed by resection while the other kidney was removed radically, by transabdominal approach.

Ureter and bladder replacement following radical cystectomy.

During the course of Hautmann-type bladder replacement, left sided ureter damage necessitated ureter replacement as well, modifying the removal of the ileum-bladder. The proximal 20 cm length of the 70 cm long isolated ileum portion was not detubularized; instead it was slipped through the mesosigma and mesocolon to the left side of the colon and the left ureter stub was anastomized without tautness to the ileum according to Le Duc. The implantation of the right ureter was accomplished according to Hautmann.
