ESWL 治疗 输尿管结石失败原因分析
[Methods] 789 cases with ureteral calculi were treated by endourological technique from October 1999 to July 2004. [Results] 738 cases were treated successfullly in situ with the rate of 93. 54% (70.58% in upper ureter, 95. 78% in middle ureter, 97.65% in lower ureter) and the stone free rate with in 3 months was 93.00%.

Ureteroscopic holmium: YAG laser lithotripsy for managing ureteral calculi (A report of 168 cases)
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.
It was suggested that ureteroscopic holmium: YAG laser lithotripsy is a highly effective and safe treatment modality for managing ureteral calculi.
It can be concluded that in a situation with urothelial damage such as ureteral calculus, urine can penetrate subepithelially and induce degranulation of mast cells with release of mediators.
Urography was required as a pre-lithotripsy procedure (n = 4) and to confirm non-dilated ureteral calculus obstruction uropathy (n = 2).
Renal colic, defined as acute flank pain caused by the passage of a ureteral calculus, is a common condition, but the correct diagnosis may not be apparent clinically.
An IVU was regarded as positive if any of the following were identified: delayed filling, hydronephrosis, hydroureter, ureteral calculus, or extravasation of contrast.
A NCHCT was regarded as positive if any of the following were identified: hydronephrosis, hydroureter, ureteral calculus, or perinephric or ureteral inflammatory change.
We report a 52-year-old woman with a right renal pelvic stone, mimicking a left upper ureteral stone in a kidney-ureter-bladder film.
The stone-free rate for ureteral stone units was 87.5%, but was 75% for bladder stones.
Nevertheless, further studies are indicated in order to evaluate as to whether there might be a use for PDE5 inhibitors in the treatment of ureteral stone disease.
Some studies have reported the effectiveness of pharmacologic therapies (calcium antagonists or alpha-blockers) in facilitating ureteral stone expulsion after ESWL.
Medical therapy following ESWL to facilitate ureteral stone expulsion results in increased 1- and 2-month stone-free rates and in a lower percentage of those needing re-treatment.
