Abstract

In an effort to study the underlying diseases, management and postoperative complications of nephrectomized patients, author analyzed the records of 171 nephrectomized patients who were treated at the Department of Urology, Kyungpook National University Hospital during the past 10 years. The results were as followers: 1. These 171 nephrectomized patients revealed giving rate of 14.9% to the total urologic operations during above periods. 2. The most frequent year distribution was 1981, being 31 patients, followed in frequency by 1980 in 29 and 1979 in 25. Over half of nephrectomized patients were seen since 1979. 3. The most commonly involved age group was the 3rd decade (24.6%), followed in decreasing order of frequency by 6th decade (18.1%) and 4th decade (17.5%). Sex ratio. male to female, was 1.9:1. 4. The most common causative disease was the tumor comprising 43 patients (25.1%) out of 171 nephrectomized patients, followed in order of frequency by renal injury in 40(23.4%), renal tuberculosis in 33(19.3%), renal infection in 21(12.3%) and hydronephrosis in 16(9.4%). 5. The most frequently employed surgical approach of nephrectomy was through translumbar (64.3%), followed by transperitoneal (30.4%), thoracoabdominal (4.7%) and posterior lumbar (0.6%). The translumbar approach was undertaken nearly in all nephrectomized patients except transperitoneal approach in 18 tumor patients, thoracoabdominal in tumor patients and transperitoneal approach in 26 renal injury patients. 6. Postoperative complications were developed in 21 patients and 2 of these were died. 7. One hundred and forty one patients (82.5%) were hospitalized between 8 and 21 days, 24 over 22 days and 6 below 7 days.
