Renal Tumor Biopsy Technique

Tumor Seeding With Renal Cell Carcinoma After Renal Biopsy

Tumor seeding following biopsy of renal cell carcinoma is extremely rare with an incidence of 1:10.000. In this paper two cases with multiple recurrent RRC metastasis in the biopsy tract following biopsy of renal tumor is presented and the current literature is shortly discussed.

Soft-tissue Biopsy Technique

The instrument described here consists of a special syringe on which sharp cutting needles of various sizes are mounted. These produce undistorted biopsy specimens. Suction is used only to retain the specimen within the needle, and the cleancut cylinder of tissue is quite unlike that obtained by aspiration. Gillman and Gillman&2 used this principle for their liver biopsy instrument. We have ret...

Renal Tumor Biopsy for Small Renal Masses: A Single-center 13-year Experience.

BACKGROUND Renal tumor biopsy (RTB) for the characterization of small renal masses (SRMs) has not been widely adopted despite reported safety and accuracy. Without pretreatment biopsy, patients with benign tumors are frequently overtreated. OBJECTIVE To assess the diagnostic rate of RTBs, to determine their concordance with surgical pathology, and to assess their impact on management. DESIG...

Transjugular renal biopsy.

A novel technique to obtain renal biopsy specimens from patients in whom percutaneous renal biopsy is contraindicated is described. After adaptation of equipment used for transjugular liver biopsy, 50 such patients underwent transjugular renal biopsy: specimens of renal tissue were obtained from 44 patients, and glomeruli were found in 38 specimens. No major complications were observed and hist...
