1/24. Cystic renal cell carcinoma diagnosed by cystofiberscopy.A 64-year-old man suffered from hypertensive syncope and was admitted to Branch Hospital, faculty of medicine, The University of tokyo. On admission he had no symptoms; however, two renal cysts of about 5 cm in diameter were found in his left kidney. Cystofiberscopy with a thin optical fiberscope was performed in addition to puncture and cystography. Cytology revealed class I, but the wall surface of the lower cyst was uneven, fluid-filled, colloid-like and white-gray compared with that seen in the upper cyst. It was diagnosed as renal cell carcinoma (RCC) and left nephrectomy was performed (5 cm in diameter, RCC, papillary tubular, common, clear cell subtype, G2>G1, INF beta, pT2, pMx, pV0, ew(-)).- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
2/24. Needling renal cysts and tumours: cytology and radiology.Renal masses found by intravenous urography, ultra-sound scanning, and arteriography were needled in 102 patients. Simple renal cysts containing clear fluid and no cytological abnormalities were found in 85 patients. Two unsuspected renal cell carcinomas were found on puncture; cytological examination showed malignant cells in the aspirate. Another five renal tumours were needled deliberately before nephrectomy, and a firm preoperative diagnosis of renal cell carcinoma was made on aspiration cytology in three. Benign cysts which had bled were particularly hard to diagnose. With care, radiology and cytology in combination can provide the firm diagnostic base needed for sound clinical management. The radiology-cytology team must be alert to the unusual finding that indicates a complex lesion, such as an unsuspected renal tumour.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
3/24. Percutaneous unroofing of renal cysts.Renal cyst is a common renal disease. It rarely produces symptoms, and thus rarely requires treatment. Treatment becomes necessary when the cyst is symptomatic or complicated. The possible approach includes surgical unroofing or cyst puncture without or with intracystic injection of sclerosing agents. This is a report on the percutaneous unroofing for the treatment of symptomatic or complicated renal cysts.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
4/24. Hyperdense renal cyst due to prolonged retention of iodinated contrast material: case report.A case of a hyperdense renal cortical cyst resulting from cyst puncture and opacification 28 months previously is reported. Prolonged retention of water-soluble iodinated contrast material is an unusual cause of a hyperdense renal cyst, which has not previously been described. The findings on serial computed tomography (CT) and chemical analysis are presented and discussed.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
5/24. Renal cyst puncture: a non-diagnostic procedure in the infant.A case of metastatic wilms tumor in a newborn is presented. Cyst puncture was included in the preoperative evaluation and the merits of this procedure in infants are questioned. The differential diagnosis of intrarenal masses in the neonate is discussed.- - - - - - - - - - ranking = 5keywords = puncture (Clic here for more details about this article) |
6/24. Puncture of unilateral renal cyst in utero.Although most authors do not recommend prenatal puncture of a unilateral single cystic renal mass, in case the contralateral kidney is normal and there is sufficient amniotic fluid, this case report shows that the procedure, which can be done very carefully under ultrasonic guidance, can be helpful in establishing the presumed diagnosis.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
7/24. Simple renal cysts in infants.Two cases of renal cysts in infants less than one year of age are presented. In both instances percutaneous puncture of the cyst aided in establishing the diagnosis without the need for an operative procedure.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
8/24. Echo-free renal masses on ultrasound: the stethoscope as an adjunct to their diagnosis.A patient with an intrarenal arteriovenous malformation is described. Ultrasound suggested this to be a renal cyst but auscultation revealed a loud bruit and, on the basis of this, arteriography rather than cyst puncture was carried out.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
9/24. Evaluation of perihilar and central renal masses using the Chiba needle.The Chiba needle was used to puncture 14 central renal masses believed to be cysts. Of these masses 13 were cysts and 1 was a peripelvic liposarcoma. Arteriography was not done before puncture. No complications occurred when these central masses surrounded by parenchyma or adjacent to hilar structures were punctured. Renal cyst puncture and cystography using the Chiba needle are safe methods for optimal diagnosis of central and peripelvic systs.- - - - - - - - - - ranking = 4keywords = puncture (Clic here for more details about this article) |
10/24. Renal hydatid disease: report of 9 cases and discussion of urologic diagnostic procedures.Nine cases of renal hydatid disease are reported. All diagnostic procedures are discussed and the important role of ultrasound renal scan and cyst puncture is emphasized. Although it is rare, renal secondary location has to be suspected in cases of hepatic echinococcosis and conservative surgical treatment is required to preserve renal function.- - - - - - - - - - ranking = 1keywords = puncture (Clic here for more details about this article) |
