Renal surgery on anatomical basis: I Study of pelvic-alyceal system

ABSTRACT

150 human kidneys of different ages and sex [60 specimens for plastic corrosion, 20 specimens for thick white gelatine methods] were used as well as 70 I.V.U. [Intra- Venous Urography] of normal persons were studied. The careful examination of these specimens showed 5 pelvi- calyceal patterns and 3 types of the renal pelvis. It is of extreme importance to put in consideration the number and direction of the minor calyces to help the urosurgeon and radiologist in the process of percutaneous nephrolithotomy or partial nephrectomy. Also, to have some experience to be able to distinguish posterior calyces "en face" from anterior calyces "in profile" on an antero- posterior radiograph
