title: [Effects of urologic surgery on lymphocyte subpopulations].
abstract: We studied the postoperative development of lymphocytes, T cells and lymphocyte subpopulations, in peripheral blood in 45 patients. Twenty-five of them were subjected to a TUR of a bladder tumor, 10 to a transvesical prostatectomy, 6 to a pyelolithotomy and 4 to a nephrectomy for renal atrophy secondary to lithiasis. We confirm a significant postoperative drop in the lymphocyte count and in the percentages of OKT 3+ (total T cells), OKT 4+ (helper T cells) and OKT 8+ cells (cytotoxic/suppressor T cells) 2-4 hours after the operation. Its duration varies according to the type of operation carried out. Despite the slight differences observed in the postoperative development of the lymphocyte subpopulations, at no time in the study did we report significant postoperative variations in the OKT 4+/OKT 8+ quotient.
