To determine the current state of kidney transplantation (KT) training in a country that is leader in organ donation and transplantation. ⋯ The surveyed residents demand more training in KT. The most common situation is to end a residency without having performed a complete KT. KT is considered an asset when selecting a resident medical intern position and commonly they are part of the transplantation team. The majority of residents are trained in centers with less than 75 transplants/year. External rotations in KT are not the rule in centers where transplantation is not performed.

Randomized Controlled Trial Comparative Study
Comparison between retrograde intrarenal surgery and extracorporeal shock wave lithotripsy in the treatment of lower pole kidney stones up to 15 mm. Prospective, randomized study.
Extracorporeal Shock Wave Lithotripsy (ESWL) is currently the recommended treatment for intra-renal calculi smaller than 2 cm. However the low Stone Free Rate (SFR) in lower pole calculi gives rise to new techniques, such us retrograde intrarenal surgery (RIRS), for improve the surgery outcomes. ⋯ In the treatment of lower pole stone RIRS has the same results than ESWL in terms of SFR. Regarding absence of a clinically significant residual fragment, RIRS was superior to ESWL. A bigger sample size is required in order to confirm this results.

Comparative Study
(11)C-choline PET/CT and multiparametric MRI in patients with biochemical relapse of prostate cancer.
To assess the diagnostic usefulness of (11)C-choline PET/CT vs. multi-parametric MRI in the prostate cancer relapse. A retrospective study of 21 patients with prostate cancer treated initially with surgery (n=12), radiotherapy (n=9). PSA levels were increased (post-surgery: .3-3.6 ng/ml; post-radiotherapy: 2.4-8.8 ng/ml). In an interval of time of 15 days all patients were underwent to: whole-body-dual-modality PET-CT carried out early after (11)C-choline (296 ± 29 MBq) injection, and multiparametric prostate MRI with paramagnetic intravenous contrast (using anatomical imaging sequences, diffusion-weighted imaging and dynamic contrast-enhanced imaging). On the basis of our results, all patients were underwent to directed diagnosis and/or clinical, analytic and imaging follow-up. In 15 patients (71.4%) both procedures showed concordant results: 4 negative and 11 positive cases [7 local recurrences, 3 isolated pelvic lymph nodes (2 infracentimetric), 1 local relapse and only one M1 bone metastases]. The results were discordant in 6 patients (28.6%): 3 local relapses in MRI with no PET significance, 1 local relapse in PET with no MRI significance. 2 bone metastases were identified with PET (out of the field-of-view of MRI). ⋯ (11)C-choline PET/CT and multi-parametric MRI play a complementary role in the detection of local relapse in prostate cancer patients, with similar sensitivity for the detection of lymph involvement. Whole-body 11C-choline PET/CT technique is also useful for bone staging.

Clavien-Dindo classification system has been proposed to grade perioperative complications in percutaneous nephrolithotomy. The complications of this technique that have taken place in the last 2 years are reported in this paper according Clavien-Dindo classification. ⋯ A graded classification scheme for reporting the complications of percutaneous nephrolithotomy is useful for monitoring and reporting outcomes. We propose a standardized use of this classification in order to make the results comparable among different centers performing the technique.

To improve the predictive efficacy of the D'Amico risk classification system with magnetic resonance imaging (MRI) of the pelvis. ⋯ MRI data significantly improves the predictive capacity of BPFS when using the D'Amico model data.
