External Physical Vibration Lithecbole Versus Traditional Row of Stone After Extracorporeal Shockwave...

Renal Calculi

The traditional stone row method comprises increasing exercise, drink lots of water, drug row of stone and stone row position. External physical vibration lithecbole(EPVL) is a non-invasive device active row of stone, the researchers hope that through this test prospective clinical study to evaluate the effectiveness of in vitro physical vibration row of stones after extracorporeal shockwave lithotripsy(ESWL) treatment of stones discharged, thereby improving after ESWL stone clearance rate.

Tip-flexible Semi-rigid Ureterorenoscope Versus Flexible Ureteroscopy in Renal Calculi

Renal Calculi

This study evaluates the safety and efficacy of the novel tip-flexible semi-rigid ureterorenoscope for the treatment of renal calculi using a prospective, randomized multicentre trial design. Half of participants will receive retrograde intrarenal surgery using the tip-flexible semi-rigid ureterorenoscope, while the other half participants will receive retrograde intrarenal surgery using the classic flexible ureteroscope.

Citrate Salts for Stone-free Result After Flexible Ureterorenoscopy for Inferior Calyx Calculi

UrolithiasisCalyx; Calculus

The prevalence of urolithiasis is around 10 % in the French population. It is thus a major public health issue. When the stone is not spontaneously removed, interventions such as extracorporeal lithotripsy or flexible ureteroscopy (F-URS) are performed. F-URS is usually preferred in renal stones > 7 mm in comparison with lithotripsy, with better results. Efficacy of ureteroscopy is based on the "stone-free rate" (SFR) at 3 months. A SFR index is assessed according to the existence of residual fragments and their size. SFR score 1 (fragment ≤ 1mm) has been poorly studied, and is supposed to occur in 60% of cases. These residual fragments account for the high frequency of recurrence, probably favored by crystals aggregation and growth of these fragments under supersaturated urines. Indeed, calcium stones risk factors are urine supersaturation and crystal growth inhibitors deficiency. Citrate is the major crystal growth inhibitor in human urine. A hypocitraturia is reported in half of the lithiasic population. Consequently, citrate salts appear as an interesting therapeutic option, in order to slow crystal growth but also to chelate calcium, and consequently to solubilize stones in situ. However, to date, there is no available controlled study after surgical intervention such as flexible ureteroscopy. The aim of the investigator's study is to evaluate the efficacy of a 3-month potassium and magnesium citrate treatment following ureteroscopy on the elimination of residual fragments (SFR score 1).

Urinary Calculus

The purpose of this study is to compare the stone clearance rate treated with different drugs after ESWL in urinary calculus,These drugs are often used in urinary calculus,such as progesterone,tamsulosin,propantheline Bromide and nifedipine.In these study the investigators want to investigate different effect of these drugs use to treat urinary calculus after ESWL.

Percutaneous Nephrolithotomy for Treatment of Kidney Stones Greater Than 2 cm

Renal Stone

Percutaneous nephrolithotomy (PCNL) is a minimally invasive procedure considered as the treatment of choice for the management of large-scale and fully-formed kidney stones.This procedure has a 5% risk of complications including bleeding, the lesion of the collecting system, the risk of urinary infection and bacteremia. New surgical tools such as dilatation of the nephrostomy tract with mechanical dilatation contribute to the reduction of these risks, together with an improvement in the operative times and a lower rate of complications. At present there are multiple scales measuring the lithiasic morphology (Guy, the STONE nephrolitometry score system and the nomogram of the Office of Clinical Investigation of the Endourology Society - CROES) which allow to evaluate the degree of complexity of the stone, the possibility of residual stones and the risk of complications. These tools allow us to do a better analysis of the risk factors of the patient who will be taken to this type of endoscopic procedure in order to decrease morbidity and complication rates. Hypothesis: The use of pneumatic dilators during percutaneous nephrolithotomy reduces the rates of intraoperative and postoperative complications, which would have an impact on hospitalization times and surgical success for the management of renal stone.
