[Analysis of urinary tract injury during gynecological surgery performed with preoperative ureter catheterization or intraoperative ureter control]. / Analiza czestosci wystepowania uszkodzen ukladu moczowego w czasie wybranych operacji ginekologicznych po zastosowaniu przedoperacyjnego cewnikowania moczowodów oraz sródoperacyjnego ustalania ich umiejscowienia.

DESIGN: To analyze urinary tract injuries during gynecological surgery performed with preoperative ureter catheterization or intraoperative ureter control. MATERIAL AND METHODS: Retrospective analysis of 1986 chosen gynecological operations performed between 1990-1998 in Dept. of Gynecological Surgery Polish Mother's Health Center Institute. RESULTS: The overall frequency of urinary injuries was 2.15%. It was less during gynecological surgery performed with ureter catheterization compared to intraoperative ureter control only (ureter: 0.30% vs. 0.55%, p = 0.22; urinary bladder: 0.40% vs. 0.90%, p < 0.05). CONCLUSION: 1/ urinary injury was twice as frequent during ureter control than during ureter catheterization, 2/ urinary injury was the most frequent complication during hysterectomy with adnexa, 3/ the results of our analysis should be treated as a vote "for" ureter catheterization before gynecological surgery.

[Pregnancy and delivery in a patient after ileocystoplasty]. / Ciaza i poród u pacjentki z jedna nerka po ileocystoplastyce. Opis przypadku.

We report a case of successful pregnancy and delivery in 22 year-old patient after several surgeries in urinary tract including left nephrectomy in the past. Ileocystic reservoir with appendectomy for cathetering every two hours was performed, because of neurogenic bladder hyperactivity, caused by spina dystrophy.

Usefulness of non-invasive diagnostic methods for early detection of neoplasms of the urinary tract and male genitals among workers of the Mazovian Refining and Petrochemical Plant in Plock.

The studies were aimed at the evaluation of the usefulness of non-invasive diagnostic methods including inquiry, clinical examination, transabdominal ultrasonography, cytologic examination of the urinary sediment, determination of blood serum concentrations of certain neoplastic markers, and urinalysis for early detection of neoplasms of the urinary tract and male genitals; and at the determination of the sensitivity and specificity of percutaneous ultrasonography combined with cytologic examination of the urinary sediment for detection of neoplasms of the kidneys and urinary tract, particularly of the urinary bladder. Urological examinations were performed in 300 workers occupationally exposed to oil derivatives. Neoplasms of the urinary tract and male genitals were detected in 37 (12.3%) workers. Neoplasms of the urinary bladder were found most frequently. They were diagnosed by non-invasive methods in 14 (4.7%) and verified clinically and histologically in 11 (3.7%) persons. The results seem to indicate the usefulness of non-invasive diagnostic methods for urological screening studies among occupational populations with increased risk of neoplasms of the urinary system and male genitals. The high sensitivity (93%) and high positive predictive coefficient (0.90) for the combination of transabdominal ultrasonography and cytological examination of the urinary sediment for detection of urinary system neoplasms seem to be tokens of their high diagnostic value and clinical usefulness.

Usefulness of digital subtraction angiography for diagnosis of renal tumours.

DSA (digital subtraction angiography) is a new, highly effective method for visualization of kidney vascular system. By means of a digital subtraction angiography unit the image of bones and soft tissues is blotted out, and a subtractive picture of contrasted vessels alone emerges. Intra-arterial DSA is a less invasive and more comfortable method when compared to conventional angiography. Only 2-4 ml of contrast medium is administered, thinner catheters being employed at the same time. The examination can also be performed through intravenous administration of contrast medium. The DSA unit Angiotron CMP was installed at the Department of Radiology, Military Medical Academy of Lódz, in 1984. In the present material a diagnostic DSA investigation was performed in 22 patients with renal tumours. In 21 of them the tumour was correctly diagnosed on grounds of pathological vascularization and the result was dubious in only 1 patient with benign tumour.
