Study of the Benefits of a Short Spa Treatment on the Elimination of Residual Lithic Fragments After Treatment

Not Applicable

Terminated

• Conditions: Calculi, Urinary

• Registration Number: NCT04031911
• Lead Sponsor: GUILLEMIN Francis, MD

Brief Summary

Current urological therapeutic modalities are represented by extracorporeal lithotripsy (ECL), rigid (URS) or flexible (URSsple) uretero-renoscopy and percutaneous nephrolithotomy (PCNL).

They make it possible to extract the vast majority of stones by minimally invasive techniques but leave behind small residual lithic fragments (FR) that can always cause pain, infection, or promote the development of a larger stone.

A non-invasive technique that can help eliminate them would be of great benefit to many patients by avoiding painful recurrences and limiting reprocessing; combined with appropriate medical management, it would limit the rate of remote recurrences and long-term complications.

The treatment called "hydro-posturotherapy" has been developed in some spas that are approved for kidney diseases such as Vittel or Capvern. It includes several modalities: posturotherapy, lumbar percussion and hyperdiuresis.

The main objective is to compare at 3 months, on the unprepared abdomen (ASP) and the low-dose scanner without injection, the elimination of kidney stone fragments under the effect of a short spa treatment with posturotherapy, lumbar percussion and controlled hyperdiuresis compared to the recommended standard treatment. The result will be assessed in 3 categories: complete elimination (SF: "without fragments" or "stone-free"), elimination of more than 50% of the fragments; elimination of less than 50% of the fragments.

Detailed Description

Randomized multicenter controlled clinical trial comparing hydroposturotherapy in short thermal cure with standard hyperdiuresis in patients with residual stones, especially lower caliciels after urological treatment.

Primary Outcome Measures

Name	Time	Method
Rate of SF patients (without fragment / stone free) in each arm, on the scanner and on the ASP.	3 months after the patient's urological management	Estimate of the rate of patients for whom all fragments have been eliminated

Secondary Outcome Measures

Name	Time	Method
Number of participants with complications related to residual stones or their evacuation	At inclusion, 1 month after inclusion, 3 months after inclusion	Complications may include renal colic, low back pain, urinary tract infections
Medico-economic study of the benefit of the thermal cure	3 months after inclusion of patients in the cure group	Study of the benefits of hydroposturotherapy in terms of avoided management costs
Size of residual fragments in the cavities of the treated kidney at 3 months.	3 months after the patient's urological management	The size of the residual fragments will be measured in millimetres
Quality of life questionnaire SF 36 : The Short Form (36) Health Survey	At inclusion, 1 month after inclusion, 3 months after inclusion	The SF 36 questionnaire is a questionnaire measuring quality of life with 36 items grouped into 8 scales: physical activity, limitation/physical state, physical pain, perceived health, vitality, life/relationships, psychological health, limitation/psychological state; The SF-36 is not suitable for producing an overall summary score. Indeed, the information in the individual responses is lost in the total score of the scale (since the total score can be obtained in different ways from the individual responses of the items). The recommended rating system for SF-36 is a Likert weighted system for each item. The items in the subscales are totalled to obtain a summary score for each subscale or dimension. Each of the 8 summary scores is linearly transformed on a scale from 0 (negative for health) to 100 (positive for health) to obtain a score for each subscale.
Number of intercurrent events	At inclusion, 1 month after inclusion, 3 months after inclusion	renal colic, infection, hematuria), work stoppages, medical prescriptions, hospitalizations, urological procedures.
