In haematuria blood clots may form in the renal pelvis, with risk of outflow obstruction, impairment of renal function, pain and infection. The clots can also provide a matrix for stone formation. Ureteral catheterization and/or pyelostomy may be required if clots are not spontaneously excreted. Based on experience from a case of intrapelvic clotting due to haematuria after renal biopsy, a technique of coagulolysis is described. Via a ureteral catheter a solution of serum and streptokinase was intermittently infused into the renal pelvis. The case is presented. The clots disintegrated within 48 hours and urinary excretion recommenced, with reversal of rise in the blood creatinine level. There were no complications from the procedure, which seems to be a satisfactory alternative to surgical evacuation of clot.
在血尿中，血凝块可能在肾盂中形成，存在流出道梗阻、肾功能损害、疼痛和感染的风险。血凝块还可为结石形成提供基质。如果血凝块不能自行排出，可能需要进行输尿管插管和/或肾盂造瘘术。基于一例肾活检后血尿导致肾盂内凝血病例的经验，描述了一种凝块溶解技术。通过输尿管导管将血清和链激酶溶液间歇性注入肾盂。现呈现该病例。血凝块在48小时内分解，尿液排泄恢复，血肌酐水平升高的情况得到逆转。该操作无并发症发生，似乎是手术清除血凝块的一种令人满意的替代方法。
