Patient: description of the condition (onset time, main symptoms, hospitalization, etc.): patient female, 48g,occurred twice in the past half a month, right lumbar pain in the early hours of the morning, dry heaving. Pain relief with painkillers, symptomatic treatment; examination ultrasound suggests that the left kidney section morphology is normal, the university 9.8 * 4.5cm collecting system separation 1.0cm, the right kidney section morphology is not clear, the collecting system separation 4.6cm. Renal pelvis imaging: plain film shows: the right mid-ureteral region can be seen in the right ureteral region of the 12.* 0.7cm2 size of high-density shadows. Plain film shows: secretion of the right kidney is obviously prolonged, the renal pelvis and calyces are obviously enlarged and blurred, and the right ureter seems to be thickened and obstructed with the middle part [the area shown in the plain film]. The left kidney had normal secretion, the renal pelvis and calyces were well displayed, and the ureter was smooth, with no obvious signs of obstruction. In 2008, because of the mild hydronephrosis of both kidneys of a little more than one point each, bilateral ureteral stones, in the local hospital applied holmium laser lithotripsy, 40 days after the operation, the right hydronephrosis of 1.2, the right ureter there is a 0 point a few stones, stones with extracorporeal lithotripsy did not see any improvement. What should we do now? The local hospital suggested holmium laser lithotripsy again, does it affect the ureter? Can we still do it this time? Can you give some treatment suggestions? Sun Fa, Department of Urology, Affiliated Hospital of Guizhou Medical University Sun Fa, Department of Urology, Affiliated Hospital of Guiyang Medical College: You are suffering from right hydronephrosis caused by right ureteral stone, which should be treated as soon as possible. No matter what methods are used, the aim is to make the right ureter open and improve the right hydronephrosis, which will lead to loss of the right renal function if it is not treated in time. At present, the right kidney function has been impaired, so it should be treated as soon as possible. Firstly, ureteroscopic lithotripsy can be chosen, percutaneous nephrolithotripsy can also be used, and secondly, laparoscopic lithotripsy or open surgery can also be used to remove stones! Patient: just check the kidney function is still normal, thank you Professor Sun Sun hair of the Department of Urology, Affiliated Hospital of Guiyang Medical College: you check the total kidney function, not the right kidney function, so go to the hospital as soon as possible to deal with. Patient: Professor Sun, now in our local hospital to do holmium laser minimally invasive surgery, is 4 days after surgery, but the postoperative continuous bladder flushing, exercise a little more will see from the ureter to stay out of the liquid is red, daytime drainage color is lighter, every night, the color of the drainage fluid will be darker, this is why, what should we pay attention to. Thank you Sun Fa, Department of Urology, Affiliated Hospital of Guiyang Medical College: It should not be a big problem, temporarily reduce the amount of activity, generally about a week will be significantly better. No matter what your ureter should be retained in the double J tube, if so estimated future activities may have hematuria, as long as it is not very red, drink more water can be, after the removal of the tube will naturally improve. Patient: Thank you, Prof. Sun
