泌尿器科領域に於ける血清電解質の研究 第III篇: 諸種泌尿器疾患に於ける術前,術後の血清Na,K,Ca濃度の変動

Abstract

The following results were obtained by measuring the levels of serum sodium, potassium, and calcium in the preoperative period and at 24 hours, 48 hours, 5th, 8th, and 14th days in the postoperative period in order to evaluate the effects of surgical operations and excision of the ill site on 103 surgical cases. 1. Effects of surgical operations on t h e levels of serum sodium, potassium, and calcium The serum electrolytes levels were measured by the flame photometer in the pr e o perative period and at 24 hours, 48 hours, 5th, 8th, and 14th days in the postoperative period on nephrectomy (20 cases), renopexy (2 cases), nephrolithotomy (5 cases), pyeloureterolithotomy (10 cases), total cystectomy (10 cases), total prostatectomy (7 cases), meatotomy (2 cases), urethroplasty (4 cases), epididymectomy (3 cases), orchidopexy (1 cases). i). The serum sodium was decreased in 80-100 per cent of the cases. Its level was lowest at 24-48 hours in the postoperative period, then it gradually increased and it reached the normal range on 8th day. ii). The serum potassi u m was increased in 90-100 per cent of the cases. Its level was highest in 80-90 per sent at 24-48 hours in the postopeative period, then it gradually decreased, and it reached the normal range on 8th day. iii). Consistent change in the serum calcium lev e l was not observed, though it slightly increased in the postoperative period and it recovered on 8th day. 2. Effects of excision of ill site on the levels of serum sodiu m potassium, and calcium. The levels of serum sodium, and calcium were measured on postoperative 1 4 th day on 103 cases. i). U rogenital tuberculosis The mean serum sodium was increased to 139.5m Eq/1, the mean serum potassium was decreased to 4.34 mEq/1, and the mean serum calcium was not significantly changed throughout the pre- and postoperative periods. ii). Urogenital lithiasis : The serum sodium were increased in o ne third and potassium of the cases, the mean value of the former was increased to 139.9mEq/L and that of the latter was within normal limit (4.45 mEq/1). The mean serum calcium was increased to 5.13 mEq/1. iii). Urogenital tumors : The serum sodium and potassium were both increased, the mean value of the former was increased to 139.0 mEq/1 and that of the latter was increased to 4.65 mEq/1. The mean serum calcium was not significantly changed. iv). Malformation The serum sodium was increased in 70 per cent of the cases, though its mean value was decreased to 139.2 mEq/1. The serum potassium was increased in 60 per cent of the cases, though its mean value was not significantly changed. The serum calcium level was within normal limit and its mean value was 4.69 mEq/1. v). Inflammatory and other diseases : The levels of serum sodium a n d potassium stayed within normal limits and mean value of the former was 135.7 mEq/1 and that of the latter was 4.52 mEq/1. The serum calcium was decreased, though its mean value was slightly decreased to 5.15 mEq/1.
