In severe cases of bilateral kidney stones, the stones may completely obstruct the ureters bilaterally, resulting in oliguria; however, in milder cases, they may not necessarily obstruct the urethra, resulting in oliguria, depending on the individual’s condition. The main treatments for bilateral upper urinary tract stones include bilateral staged and simultaneous extracorporeal shock wave lithotripsy and bilateral staged and simultaneous percutaneous percutaneous nephrolithotripsy. In recent years, with the development of endoluminal urology technology and the accumulation of experience, transureteral urethral lithotripsy combined with Holmium laser pulverized lithotripsy under direct vision together with the use of lithotripsy nets can achieve high therapeutic results. It can relieve the problem of oliguria caused by double kidney stones. After blocking the ureter, double kidney stones can cause ureter dilatation, hydronephrosis and other complications, and in serious cases, it can cause the decline of renal function, thus leading to oliguria. It is recommended that patients with double kidney stones go to regular hospitals for timely treatment to avoid deterioration of the condition.
