Abstract
Renal cell carcinoma (RCC) is considered the ninth most
commonly occurring cancer in men and the 14th most
commonly occurring cancer in women. There were over
400,000 new cases in 2018 worldwide, and represents about 2–
3% of all cancers and about 85–93% of malignant tumors of
the kidney.
The aim of the current study was to prospectively
compare ORN and OPN for mangement of organ confined
renal masses in urology department Menofia university.
Our study included 48 patients; with mean age 56.6±13.2.
Majority of cases were males 32 (66.7%), while females represented
16 (33.3%). They were divided into two equal groups; group 1
included 24 patients and was treated by PN, and group 2 included 24
patients and was treated by RN.
Most of tumors were polar 28 cases (58.3%) and mid zonal in 20
cases (41.6%) with mean size of 4.2±1.4 for PN and mean size of
5.8±1.3 for RN. There was statistically significant difference as regard
tumour size.
Regarding surgical incision we used traditional lumbar
incision in 43 patients (89.5%) and chevron incision in 5
patients of radical nephrectomy (10.6%).
Regarding partial nephrectomy we used hot ischemia
alone in 16 patients (66.7%) and we used both types of hot and
cold ischemia together in 8 patients (33.3%) with mean time of
ischemia 13.2±4.1.we used different technique included simple
