[Laparoscopic nephrectomy; results of initial 14 cases and procedure for renal cell carcinoma].
Since July 1991, we have performed laparoscopic nephrectomy for removal of damaged kidneys in thirteen patients. In addition, we recently developed a new procedure of laparoscopic nephrectomy for renal cell carcinoma and successfully removed the kidney with renal cell carcinoma. Patients' age ranged from 18 to 80 years with the average being 50 years. There were 8 male and 6 female patients. Original disease was calculous disease in 5 patients, vesicoureteral reflux in 4, renovascular disease in 2, ureteropelvic junction obstruction in 1, ectopic ureter in 1 and renal cell carcinoma in 1. The mean size of the diseased kidney was 9 x 5 x 4 cm in the initial 13 cases and 13 x 7 x 6 cm in the case with renal cell carcinoma. The size of the tumor was 2.5 x 2 x 2 cm. In the first 13 patients, nephrectomy was performed as described previously. In the patient with renal cell carcinoma, a new procedure was applied. In the new procedure, five trocars were introduced into the abdominal cavity through the lateral abdominal wall. The kidney was removed en bloc together with the adrenal gland, perirenal fat and Gerota's fascia in the same fashion as traditional radical nephrectomy. Thirteen kidneys were successfully removed, but one failed because of dense adhesion to the surrounding tissue. Three of the 13 patients required additional laparotomies to control bleeding or to remove missed stone.(ABSTRACT TRUNCATED AT 250 WORDS)
