    ABSTRACT: The authors present their own experience as well as data from the literature concerning the diagnosis and treatment of renal angiomyolipomas. In a group of 320 patients hospitalised at the Urological Clinic in 1990-1994 these tumours were diagnosed before surgery and confirmed by histological examination in 7 patients (2.2%). The group comprised three men and four women, mean age 51.7 years. Only one female patient had classical manifestations of tuberous sclerosis, the remaining patients did not have manifestations of tuberous sclerosis. Two patients were admitted with symptoms of haemorrhage into the retroperitoneum, three suffered from pain on pressure in the side and in two patients the tumour was revealed incidentally during US examination. Four patients were subjected to nephrectomy, in two enucleation of the tumour was performed and in one female patient with classical manifestations of tuberous sclerosis with a bilateral tumour conservative treatment was applied.

    ABSTRACT: At the Urological Clinic in Hradec Králové in 1990-1994 320 patients with renal tumours were admitted and treated. In 12 the tumour was bilateral (3.7%), incl. 8 patients where it was synchronous and four where it was asynchronous. Only in one female patient bilateral nephrectomy was performed, in 8 patients unilateral nephrectomy and on the other side enucleation of the tumour, in two patients bilateral enucleation of the tumour and in one patient with a malignant lymphoblastic lymphoma only unilateral enucleation of the tumour and epinephrectomy. In 10 patients histological examination confirmed a renal carcinoma, in one patient a malignant lymphoblastic lymphoma, in one female patient a bilateral multifocal oncocytoma. The patients survival was not evaluated in the report.

    ABSTRACT: At the Urological Department in Hradec Králové the authors operated in 1989-1993 287 patients with renal tumours, in 45 of them a conservative procedure was used (15.6%). The group comprises 29 men and 16 women, mean age 56.5 years. The contralateral kidney was normal in 29 patients (64%), in 5 patients nephrectomy was performed on account of carcinoma and in 9 patients (20%) the second kidney was hypofunctional (hydronephrosis, cysts). In two patients a conservative procedure was used on account of malignity of the blood. In 33 patients the tumour was enucleated (73.3%), in 12 the upper or lower pole of the kidney was resected. In 6 patients the tumour was in the first clinical stage, but in four already in T 3a (imperative indication). Twenty-seven tumours were evaluated by the histologist as medium differentiated, 2 of 35 as poorly differentiated. Thirty-five tumours were carcinomas (77.7%), 8 were adenomas, one was angiomyolipoma and in one instance the scar after PEC was removed which was not reliably diagnosed before surgery. The preoperative examination comprised also immunological examination which, however, was not made in two patients. The immunologist evaluated the criteria as favourable in 21 patients (60%), as risky in 12, incl. 6 were immunotherapy was administered. One patient developed a urinous fistula which healed on a stent. During the investigation period no local relapse was observed.

    ABSTRACT: Between 1972 to 1994 there were admitted 105 patients with blunt trauma of the kidney, 89 men and 16 women with median age 32 years. In 53 patients the left kidney was affected and in 52 of them the right side was injured. According to the grade of trauma we evaluated in 77 patients a contusion (73.3%), by 16 patients a laceration (15.2%), in 11 patients a rupture of the kidney with fragmentation of the parenchyma and in one the renal artery was injured. The mechanism leading to the blunt trauma of the kidney was following: traffic accident in 52 patients (49.5%), during sport in 20 patients (19.5%). 16 patients were injured in own home (9.5%) and 7 patients in work (6.7%). In 28 patients the trauma of the kidney was serious, by 5 of them we have done nephrectomy (17.8%), in two suture of the parenchyma (7.1%) and in further two patients heminephrectomy. After considering clinical status, grade of hypovolemic shock and finding on CT scan we prefer lately conservative steps in the treatment serious trauma of the kidney.

    ABSTRACT: At the Department of urology in Hradec Králové between 1989-1993 287 patients with a tumor of the kidney were operated on, in 45 of them (15.6%) conservatively. In this set there are 29 men and 16 women with the mean age 56.5 years. In 29 patients the contralateral kidney was normal (64%), 5 patients underwent nephrectomy for renal cell carcinoma, in 9 patients the opposite kidney was hypofunctionalised (hydronephrosis, cysts). In two patients the conservative approach was used for reasons of another type of malignancy (haematological). In 33 (73.3%) patients enucleation, in 12 patients resection of the lower or upper pole were done. The tumor was classified as T 1 stage in 6 patients, but in 4 patients already as T 3a (in patients with imperative indication). In 35 patients the tumor was moderately differentiated, in two ones with histologically confirmed renal cell carcinomas the tumors were poorly differentiated, in 8 patients there were histologically adenomas, in one angiomyolipoma and in another case scar after PCN (percutaneous nephrolithotomy). Preoperative examination included immunological examination, this was not done in two patients. Good results were obtained in 21 patients (60%), 12 patients were in high risk and 6 of them received immunotherapy. As an early complication one patient had urinary fistula, which resolved after introduction of stent. Relapse of malignancy in the screening period was not noticed.

    ABSTRACT: During the period from Jan. 1 1989 to June 30 1992 at the Urological Clinic in Hradec Králové three women with cortical adenomas were treated, the tumour being the cause of primary hyperaldosteronism. The age of the patients was 25-40 years, in one woman the tumour was on the right side, in two on the left side. All patients complained of marked muscular weakness, fatigue, one woman developed cramps of the hands when working and another patient was repeatedly hospitalized at the neurological department on account of attacks of weakness. In one patient the interval from the onset of complaints to assessment of the diagnosis was 23 years. All patients had complete examinations at specialized departments before operation, in all the diagnosis was established by biochemical examinations and CT. In all instances minor tumours--diameter 2-3 cm--were involved which were easily removed by surgery. The postoperative course in all patients was without complications.

    ABSTRACT: Patients treated at the Urological Clinic in Hradec Králové on account of carcinoma of the kidney are systematically followed up since 1962. In the submitted paper the authors evaluate patients treated during 1985-1991. During the mentioned period at the Urological Clinic in Hradec Králové 365 patients with carcinoma of the kidney were treated. In 55 (15%) invasion into the renal or inferior vena cava was proved (in 43 men and 12 women). In 38 patients the tumour with a thrombus of the inferior vena cava was on the right side, in 17 a tumour of the left kidney was removed. The right to left ratio is 2.2:1. Surgery of tumourous thrombosis depends on the level of the upper margin of the tumourous thrombus. A tumourous thrombus in the subhepatic part of the inferior vena cava can be treated either by massaging into the renal vein after obliteration of the artery or by parietal resection of the inferior vena cava. In 18 patients the authors were able to remove the thrombus by massaging into the renal vein. In 32 patients the inferior vena cava was resected. In five the tumourous invasion was not resolved, either because of extensive secondaries (in the liver and lungs) or because of direct tumourous infiltration of the wall of the inferior vena cava.(ABSTRACT TRUNCATED AT 250 WORDS)

    ABSTRACT: Patients suffering from renal carcinoma, treated at the Department of Urology in Hradec Králové, have been systematically followed up since 1962. In the present study we evaluated a group of patients treated from the year 1985 till 1991. The group consisted of 365 patients with renal carcinoma. In 55 (15%) of them invasion into the renal vein or into the vena cava inferior was found (in 43 men and 12 women). In 38 patients the tumour with thrombus in the vena cava inferior was on the right side, in 17 the tumour of the left kidney was removed. The proportion of the right side to the left was 2.2:1. The surgical treatment of tumorous thrombosis depends on the upper border line of the tumorous thrombus. The tumorous thrombus in the subhepatic segment of the vena cava inferior can be treated by its massaging into the renal vein after the obliteration of the artery or by the parietal resection of the vena cava inferior. The resection of the vena cava inferior was performed in 32 patients. In 5 patients the tumorous invasion could not be treated because of extensive metastases (into the liver and the lung) or there was a tumorous parietal infiltration of the vena cava inferior. Evaluating the whole group after 30 years inclusive of the Navrátil's set made with our cooperation, there were 1,005 patients suffering from renal tumours, operated on at the Department of Urology in Hradec Králové. In 155 (15.4%) tumorous thrombi were surgically removed from the great veins. In 38 cases there was a demarcation of tumorous thrombi to the renal vein but in 117 the thrombus penetrated into the vena cava inferior.(ABSTRACT TRUNCATED AT 250 WORDS)
