Morphologic changes in the canine urinary tract after ureteral reconstruction with the tunica albuginea (experimental study).

Objectives: The problem of ureteral reconstruction has not been fully solved, despite dramatic developments in surgical methods. Many attempts to repair a ureteral damage with autologous or homologous organ grafts, or with organic substitutes have not really been satisfactory. Also, attempts to use alloplastic and heteroplastic prostheses made of synthetic materials have been equally disappointing.

Urine cytology in patients with urinary tract calculosis.

Urinary cytological examination was performed on 375 patients suffering from urolithiasis at the Department of Urology. University School of Medical Sciences, Bydgoszcz between 01.01.

Endometriosis of the urinary bladder.

Although every seventh or eighth case of endometriosis is found to have urinary involvement, this type of endometriosis is still rarely recognized. The symptoms are not specific and are frequently suggestive of a neoplastic process. On the basis of our two cases of histopathologically two types of endometriosis as well as literature review the practical significance of endometriosis in urology is described.

[Activity of antithrombin III in the blood of patients with bladder cancer].

The activity of antithrombin III (AT III) in the blood of patients with bladder carcinoma was examined. It was shown an increase of AT III activity in comparison with control group. The changes of AT III activity in the blood of patients with bladder carcinoma can be the symptoms of an increased risk of haemorrhagic or thromboembolic complications.

[The activity of alpha-2 macroglobulin in the blood of patients with prostatic carcinoma].

The activity of alpha 2-macroglobulin in the blood of the patients with prostatic carcinoma (PC) and benign prostatic hyperplasia (BPH) was examined. It was shown an decrease of alpha 2-macroglobulin in patients with prostatic carcinoma in comparison with control group consisted of the patients with benign prostatic hyperplasia. The low activity of alpha 2-macroglobulin in the blood od the patients with PC can be a symptom of an increase risk of haemorrhagic complications.

[Antithrombin III activity in blood of patients with renal cancer].

The activity of antithrombin III (AT III) in the blood of 20 patients with renal carcinoma was examined. An increase of AT III activity in comparison with control group was observed. The increase of AT III activity in the blood of the patients with renal carcinoma can be as a result of compensatory mechanism safing these patients before thromboembolic complication.

[Diagnostic value of cytologic examination of urine sediment in patients with non-neoplastic diseases].

The results are presented of urine sediment cytological examination of all patients treated in the Department of Urology for non-neoplastic diseases from March 01, 1989 to October 01, 1991. Out of the total number of 936 newly admitted patients in 88 cases the urine cytological examination demonstrated dysplastic cells which accounted for 9.4%, while in 11 cases cells suspected of malignancy were found which accounted for 1.

[Disseminated intravascular coagulation syndrome with secondary fibrinolysis activation in prostatic carcinoma].

We reported on a 74 year old patients with local advanced prostatic carcinoma. Following prostatic surgery an increased bleeding tendency was observed. The patients showed clinical and laboratory evidence for consumption coagulopathy with hyperfibrinolysis.

[Activity of protein C in blood of patients with prostatic carcinoma].

The activity of Protein C in the blood of the patients with prostatic carcinoma and benign prostatic hyperplasia was examined. It was observed a slightly decrease of activity of protein C in the blood the patients with prostatic carcinoma. The observation of the activity of Protein C is useful because it allow to differentiate from patients with prostatic carcinoma a group of high risk of haemorrhagic complications.

[Tissue type plasminogen activator and its inhibition in blood of patients operated on for prostatic carcinoma].

In 30 patients with prostatic carcinoma a higher of t-PA, a low of PAI-1, alpha 2-antiplasmin and plasminogen activity with increased fibrin degradation products (FDP) level and a short euglobulin lysis time (ELT) were observed. Following surgery a further increased of fibrinolytic activity occurred. The activity of t-PA and PAI-1 were higher than before operation.

[Activity of alpha 1-antitrypsin in blood of patients with prostatic tumor].

The activity of alpha 1-antitrypsin in patients with prostatic carcinoma and benign prostatic hyperplasia was examined. The activity of alpha 1-antitrypsin was higher in patients with prostatic carcinoma. The higher activity of alpha 1-antitrypsin is good prognostic sign for patients with prostatic carcinoma because it is born of large defense possibilities in these patients against the disease.

[Levels of plasminogen and alpha 2-antiplasmin in blood of patients with prostatic tumor].

In the blood of 20 patients with prostatic carcinoma the level of alpha 2-antiplasmin and plasminogen were examined. The control group consisted of 20 patients with benign prostatic hyperplasia. The low activity of alpha 2-antiplasmin in the blood of the patients with prostatic carcinoma was observed.

[Activity of alpha 1-antitrypsin in blood of patients operated on for tumor and benign hyperplasia of the prostate].

The activity of alpha 1-antitrypsin in the blood of the patients with prostatic carcinoma and benign prostatic hyperplasia before and after the operation was examined. It was observed an increase of alpha 1-antitrypsin in the blood of patients with prostatic carcinoma and benign prostatic hyperplasia after the operation. In the blood patients of control group an increase of alpha 1-antitrypsin was observed too.

[Antithrombin III and alpha 2-antiplasmin in blood of patients operated on for benign prostatic hyperplasia].

The pre- and postoperative activity was studied of antithrombin III (AT III) and alpha 2-antiplasmin (alpha 2-AP) in blood of 40 patients subjected to transurethral prostatic electroresection due to benign prostatic hyperplasia (BPH). For comparison of the obtained results a control group was formed from patients with other diseases of the genitourinary system with exception of neoplasms. The activity of AT III and alpha 2-AP before the operation was similar to that in the control group.

Diagnostic value of urine cytology and urine carcinoembryonic antigen (CEA) level in the distinction between bladder cancer and urinary tract infection.

In the retrospective investigation we estimated the CEA levels in urine and urine cytology in 293 patients with urinary bladder cancer (group I) and in 129 patients with urinary tract infection (group II). An increased CEA level was found in 212 cases of bladder cancer and in 109 cases of urinary infection. Neoplastic cells in urine sediment were identified in 254 cases in the first group, while in the second, multiple inflammatory cells and pyuria were diagnosed in 55 and 56 cases, respectively.

[Bacteroides melaninogenicus, during Fournier's gangrene].

In two patients (L.C., case No.

[Levels of carcinoembryonic antigen in blood serum and in urine in employees who smoke at the "Pasamon" Industrial Works in Bygdoszcz].

CEA levels in serum and urine determined in healthy persons who were heavy smokers. We examined 215 workers of the "PASAMON" Industrial Works (186 women and 29 men). The level of CEA in serum was elevated in 19% of healthy workers smoking 10 or more cigarettes daily.

[Rare case of congenital chyluria].

A rare case is presented of congenital chyluria in a 16-year-old boy. On the basis of literature data the pathological mechanism of that disease is discussed. The clinical data and examinations carried out, particularly lymphography, confirmed the preliminary clinical diagnosis.

[Evaluation of renal function based on cytologic examination of urine sediments in industrial workers employed in a Bydgosz conveyer belt plant "Pasamon" ].

215 healthy workers, aged 19-61, of Bydgoszcz industrial plant were examined. In some patients urine sediments contained pathological ingredients, which could be an early symptom of a urinary tract disease. No traits of neoplastic processes were found.

[Levels of carcinoembryonic antigen and alpha fetoproteins in urine of of workers at the Bydgoszcz industrial works "Pasamon"].

A group of 215 healthy workers of the Bydgoszcz Industrial Works "Pasamon", aged 19-61 years, was examined. Normal values of CEA and AFP in urine were determined using the RIA method. They were 0-42 ng/ml and 0-9 UI/ml, respectively.

[Tissue plasminogen activator, its inhibitor and other parameters of fibrinolysis in blood of patients operated for mild hypertrophy of the prostate].

An increased blood fibrinolytic activity manifested by increased tissue plasminogen activator (t-PA) and decreased tissue plasminogen activator inhibitor (PAI-1) and increased FDP levels are seen in 40 patients with mild hypertrophy of prostate. Surgical treatment increased blood fibrinolytic activity manifested in the increase in t-PA, decrease in PAI-1, shortening of ELT, increase in FDP, and decrease in plasminogen and 2-AP activities. Blood fibrinolytic activity was the highest immediately after surgery with tendency to the gradual normalization.
