ABSTRACT
Introduction: The finding of an asymptomatic stone in the study of a living kidney donor does not necessarily contraindicate donation, however, there is no consensus on the management of these cases. The use of a graft with lithiasis may represent a risk of recurrence in the remaining kidney in the donor and eventual obstructive complications in the transplanted kidney. The objective of this work is to present the usefulness of ureteroscopy (URS) to resolve lithiasis ex vivo before transplantation. Material and Methods: Donors with a small, asymptomatic kidney stone and with an analysis of lithogenic factors without relevant findings were considered to continue in the donation process. The kidney unit with stone was selected for nephrectomy. Results: Four donor kidneys underwent flexible URS after nephrectomy under hypothermic preservation conditions during bench preparation. The average time of the procedure was 35 minutes and the stone was extracted in all cases without incident. The transplant was carried out in the usual way and the evolution of the recipients was without complications and with excellent renal function. During follow-up, no recurrence of lithiasis was observed in donors or recipients. Conclusions: In this experience, the URS of the donor kidney was a feasible procedure and was not associated with adverse consequences for the graft. The main advantage of this procedure is to avoid the potential risk to the recipient of an obstructive graft complication.
ABSTRACT
BACKGROUND: Upper urinary tract urothelial carcinoma (UTUC) represents 5-10% of urothelial carcinomas. It is managed with nephroureterectomy (NUR); however, kidney-sparing techniques are growingly used. AIM: To report the results of a 20-year series of NUR conducted in an academic center. Patients and Methods: Review of clinical and pathological characteristics of patients undergoing NUR between 1999 and 2020. Patients were followed for 63 months. Global survival curves (OS) and mortality predictors were established through Cox regression. RESULTS: We included 90 patients with a median age of 68 years undergoing NUR, of whom 68 (75%) had a pelvic tumor and 22 (25%) had a proximal ureteral tumor. A laparoscopic NUR was performed in 60 patients (66%). Thirty-three patients (37%) had tumors confined to the urothelium (pTa), penetrating the lamina propria (pT1) or carcinoma in situ (CIS), 10 patients (11%) had a tumor spreading to the muscle layer (pT2) and 47 (52%) had a tumor spreading to nearby organs (pT3 / T4). Average tumor size was 3.69 cm, nodal disease (pN) was present 12 patients (13%). Twelve patients (13%) received adjuvant chemotherapy. A higher mortality was observed among smokers (Hazard ratio (HR) 8.79, 95% confidence intervals (CI) 1.5-49.0, p = 0.01), patients with tumors classfied as pT≥ 2 (HR 1.09, 95% CI 0.01-1.0, p = 0.04) and those with tumors larger than 2 cm (HR 14.79, CI 95% 1.5-272, p = 0.01). CONCLUSIONS: Smoking patients, those with invasive tumors (T2-T4) and greater than 2 cm have higher mortality. Therefore, they should not be candidates for conservative management.

La mSalud permite dar acceso y continuidad a la atención y cuidado de salud a personas que por su condición o lejanía de otra manera no podrían tener, acercando al equipo de salud al punto del cuidado donde la persona requiere la atención. Este estudio experimental randomizado, cuanti-cualitativo, longitudinal, tiene por propósito diseñar un registro electrónico móvil para el cuidado domiciliario del paciente postrado. En este artículo se da a conocer la primera de 6 fases que contempla el estudio, la de determinación de requerimientos de información, permitiendo reconocer la necesidad de sistematizar procesos clínicos y administrativos, así como representar el flujo de trabajo de los clínicos y representar el cuidado de las personas en el hogar(AU)
The mHealth can provide access and continuity of health care to people who's for condition or distance not might otherwise have. It allows approaching the health team to the point where the person requires health care. This randomized experimental study, quantitative qualitative longitudinal have the purpose to design a mobile electronic health record for home care patient bedridden. In this paper discloses the first of six phases that includes the study, the determination of information requirements, allowing recognize the need to systematize clinical and administrative processes, and represent the workflow of clinical care of people in the household(AU)
