The earlier stages of renal tuberculosis sometimes heal without treatment, and this also occurs after obstruction of a calyx or at the pelvi-ureteric junction. 腎結核早期，有時(shí)可不治而愈，在腎盞發(fā)生阻塞或在腎盂和輸尿管連接處發(fā)生阻塞的情況下，也會(huì )出現不治而愈的情況。
The onset of symptoms coincides with rupture of a caseous focus into one of the calyces, causing infection of the renal pelvis and the production of an apparently sterile pyuria. 隨著(zhù)干酪樣變病灶破潰進(jìn)入腎盞，從而引起腎盂的感染，并產(chǎn)生明顯的無(wú)菌膿尿。
