OBJECTIVES: Studying the psychosocial sphere of patients who undergo any treatment allows to have more information about its repercussion and can help the choice of an appropriate and personalized treatment. Due to the absence of specific instruments at present, the objective is to design and validate a health questionnaire regarding the treatment received with ESWL. METHODS: It was carried out in 6 phases using a sample of 50 patients treated with ESWL in 2015 in our center, whom we interviewed by telephone. In phase 1 the items were proposed based on bibliographic review, in phase 2 those that scored below 7 were eliminated according to the evaluation from 0 to 10 on the items made by specialists. In phase 3, values of 1 to 5 were assigned to each item and those with corrected correlation more than 0.2 and not significant (p>0.05) discriminant power with U-Mann Whitney were eliminated. In phase 4 the reliability of the questionnaire was checked with two indexes (Cronbach's alpha and two Guttman's halves). In phase 5, the factor analysis with Varimax rotation was performed to calculate the construct validity and in stage 6, the scores were analyzed to establish reference values. RESULTS: 50 patients (32 men, 18 women). Median age 59 years (27-79), In phase 1, 35 items were proposed, 9 of which were eliminated in phase 2. The initial questionnaire with 26 items was distributed, with 18 being eliminated in phase 3. The final questionnaire was formed with 8 items. In phase 4 the results of Cronbach's alpha and Guttman's two halves index were 0.44 and 0.323 respectively. In phase 5 after factor analysis, we found 4 factors with 2 items each (background, impact of the acute picture, post-treatment, quality of life) able to explain 71.19% of the variance. The median scores of the scale, extreme values and quartiles studied in phase 6 were respectively: P50: 17 (minimum-maximum 9-25), P25: 14 and P75: 20. CONCLUSIONS: The study carried out has provided a new instrument for assessing satisfaction after treatment with ESWL with adequate reliability and validity values. Future studies will be necessary to contrast its true clinical usefulness.

OBJECTIVES: Uretero-pelvic junction (UPJ) obstruction has been classically treated by open dismembered pyeloplasty. Recently, laparoscopic (LP) and robotic pyeloplasty (RP) have become the techniques of choice for the treatment of UPJ stenosis in adult and pediatric population. Our objective in this paper is to review the results of minimally invasive surgery as the treatment of UPJ obstruction, the trend to use these approaches and the current limits of LP and RP. METHODS: A review of most relevant papers and meta-analysis about LP and RP in pediatric and adult population was performed using PubMed. RESULTS: In pediatric population, comparative studies and meta -analysis of relevant series show an overlap of results between LP, RP and open surgery in terms of success rate, rate of complications and hospital stay, being operating time shorter in open pyeloplasty compared to minimally invasive techniques. In infants and pre-school age open surgery remains as technique of choice for pediatric surgeons. In adults, comparative studies and meta -analysis of the most relevant series show also an overlap of results in terms of success rate and complication rate between LP and RP Nonetheless, minimally invasive techniques seem to offer a significant shortening of hospital stay and need for analgesics compared to open surgery, reason why laparoscopic techniques are recommended over open pyeloplasty in adult population. CONCLUSIONS: In view of published literature, minimally invasive surgery has been postulated as the standard treatment in UPJ stenosis, with superimposable results to open surgery. The high cost of robotic approach limits its use in this type of pathology.

Factors in addition to the disease stage pT3-pT4 in patients with localized RCC are important, such as the presence of haematuria and lymphocytic or vascular invasion for DFS. A Furhman grade of 3¿4 and the presence of tumor necrosis are especially relevant for DFS and CSS.

The density, maximum diameter and pyelocaliceal location of the stones are determinant factors in terms of the effectiveness of treatment with ESWL. Using these variables, which can be obtained in advance of deciding on a treatment, the designed risk model provides a precise approach in choosing the most appropriate treatment for each particular case.
