This paper analyzed the clinical data, diagnosis and treatment of 4 asymptomatic patients with ureteral calculi without hydrops in our hospital from October 2018 to January 2019, and comprehensively discussed the previous literature. The 4 patients in this group had no obvious clinical symptoms, no positive stones were found in the B-ultrasound of the urinary system, and no hydroureter and hydroureter of the affected side was found. Urinary CT scan confirmed ureteral stones. They were all located in the lower ureter, and the stones obstructed the lumen. The stones were round and smooth, and there was no obvious hyperplasia and edema in the surrounding mucosa. The lithotripsy was completed in the first-stage operation, and the DJ catheter was left behind for one month after the operation. Based on the clinical diagnosis and treatment process of the 4 cases of asymptomatic calculi in this group and the analysis of previous studies, these patients were mostly detected by imaging examinations or other systematic imaging examinations during the regular review of urinary calculi. Ureteral stones with obstruction did not necessarily have stone-related symptoms. The onset of renal colic involved an increase in intraluminal pressure, related stimulation of nerve endings, smooth muscle spasms caused by stretching of the ureteral wall, and systemic changes in cytokines and related hormones. Cascade reactions, etc., were associated with the movement of stones down. Ureteral stones without hydrops were mostly located in the lower ureter, which had a certain buffering effect on obstructive pressure. Asymptomatic ureteral calculi could also induce irreversible damage to renal function, and the proportion of damage increased with the diameter of the stone. Patients with a history of urinary calculi, especially those with asymptomatic stones for the first time, should be paid attention to during clinical follow-up. At present, there are few research reports on asymptomatic and non-accumulating ureteral calculi. We analyze the clinical diagnosis and treatment process and characteristics of this group of patients combined with previous literature to provide a reference for the diagnosis and treatment of such patients.

The effectiveness and safety of ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi was evaluated. Ureteroscopic holmium. YAG laser lithotripsy was performed in 168 ureteral calculi (upper 27 cases, middle 33 cases and lower 108 cases). The results showed that the stone-free rate was 92.6% in the upper ureteral calculi, 93.9% in the middle ureteral calculi and 94.4% in the lower ureteral calculi, respectively. The complication rate was 4.8% (8 cases). It was suggested that ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.

From April to October, 1988, 34 patients with ureteral calculi more than O.5 cm or smaller but impacted ureteral stone underwent pulsed dye laser lithotripsy under ureteroscopy. The results were as follows : 1. The locations of stone were upper ureter in 9(26.5%), mid ureter in 8(23.5%), lower ureter in 11(32.4%), and UVJ in 6(17.6%). 2. The success rates according to location were 66.7% in upper ureter, 87.5% in mid ureter, 91% in lower ureter, and 100% in UVJ and the average success rate was 85.3%. 3. The success rates according to stone size were 83% in 0.3-0.5 cm, 90% in 0.5-1.0 cm, and 75% in 1.0-2.3 cm. 4. The average procedure time was about 85 minutes, with a range of 30 to 120 minutes and the average hospitalization after laser therapy was about 3 days, with a range of 1 to 6 days. 5. There were 5 cases (14.8%) of failure due to upward migration of stone in 3 cases, ureteral injury in 1 case and ureteral stricture in 1 case. 6. Complications occurred in 10 patients (29.5 %), almost by ureteroscopy but laser induced complication was not found. Therefore, we confirm that laser lithotripsy is a safe and effective method for treatment of ureteral stone.

OBJECTIVETo investigate the therapeutics of complex calculi in solitary kidney, and to improve the effect and safety of treatment.

METHODSExperiences in the treatment of 42 patients were summarized. All patients were with mould or multiple calculi, 8 cases were complicated with ureter calculi, and 6 cases were hospitalized because of obstructive anuria. The patients with mould calculi received extracorporal shock wave lithotripsy (ESWL) prior to percutaneous nephrolithotomy (PCNL). While the patients with multiple calculi received PCNL prior to ESWL. Some cases were treated by lithotripsy.

RESULTSThirty-six cases (86%) were cured by ESWL combined with PCNL. Eleven cases received lithotripsy during PCNL. The 6 cases with obstructive anuria recovered in 12 hours after emergent ESWL or lithotripsy; 6 cases (14%) underwent open operation because of deformity or obstruction in renal pelvis and ureter; 2 cases have to keep nephrostomy because of repeated infection. Followed up 6-18 months, 38 cases (86%) keep good kidney function; 5 cases (14%) had renal insufficiency; 4 cases (11%) reoccurred calculi.

CONCLUSIONSThe therapeutics of ESWL combined with PCNL may clear complex calculi of solitary kidney effectively and safe. It is necessary to take emergent ESWL in renal obstructive calculi cases. And the patients with lower ureter obstructive calculi may take lithotripsy first. It is proper to choose open operation on the patients with deformity of renal pelvis or obstruction of ureter.
