我院自1970～1980年10年间共收治各型慢性肾炎病人208例。其中死亡23例,占11%。死亡病例中NPN>120mg%17例,80～120mg%3例,45～80 mg%3例,全部病例均有不同程度的氮质血症。由此可见,慢性肾炎的肾功能与预后之间有密切关系。作者试图分析本组208例患者的临床表现与肾功能的关系,探索慢性肾炎的临床表现与预后之间的关系。本文慢性肾炎诊断标准、分型及肾功能均按北戴河肾炎座淡会初步方案。NPN 45～80 mg%为轻度氮质血症,81～120 mg%为中度氮质血症,120 mg%以上为重度氮质血症。 Our hospital has treated 208 cases of various types of chronic nephritis since 1970 ~ 1980. 23 of them died, accounting for 11%. Death cases NPN> 120mg% 17 cases, 80 ~ 120mg% 3 cases, 45 ~ 80 mg% 3 cases, all cases have varying degrees of azotemia. Thus, there is a close relationship between renal function and prognosis of chronic nephritis. The author attempts to analyze the group of 208 patients with clinical manifestations and renal function, and explore the relationship between clinical manifestations and prognosis of chronic nephritis. This diagnostic criteria for chronic nephritis, typing and renal function are in accordance with the initial plan of Beidaihe nephritis Block. NPN 45 ~ 80 mg% mild azotemia, 81 ~ 120 mg% moderate azotemia, 120 mg% or more severe azotemia.
