ABSTRACT

Introducción Desde 1980, la litotricia extracorpórea por ondas de choque (SWL) ha sido empleada en el tratamiento de las litiasis urinarias, ofreciendo alternativas no invasivas a las técnicas quirúrgicas. Aunque limitada por tamaño y ubicación de las piedras, su efectividad se ve afectada por varios factores. A pesar de la evolución de técnicas quirúrgicas, la SWL podría mantener su relevancia con nuevos avances. Nuestro objetivo es revisar la bibliografía existente para recopilar los mayores avances hasta la fecha en el tratamiento extracorpóreo de la litiasis. Material y métodos Se ha realizado una revisión bibliográfica no sistemática, entre los años 2017 a 2023 para obtener 26 artículos sobre 3 tipos de innovación tecnológica en litotricia extracorpórea: Burst Wave Lithotripsy (BWL), Histotripsy y Microbubble Lithotripsy (ML). Resultados La BWL emplea ondas sinusoidales ultrasónicas de menor y mayor frecuencia que la SWL tradicional. Su mecanismo de acción genera una fragmentación de mayor calidad (finos fragmentos) en lugar de generar fuerzas tensionales como en la SWL tradicional que generan líneas de fractura que dan lugar a fragmentos de mayor tamaño. Resultados en cerdos y humanos han mostrado fragmentación efectiva con buen perfil de seguridad. Basada en la tecnología de ultrasonido focalizado de alta intensidad (HIFU), la histotricia fragmenta tejido empleando fenómenos de cavitación. Han mostrado buenos resultados in vitro, aunque la formación de microburbujas que se interponen entre la litiasis y las ondas de ultrasonido son un impedimento para el progreso de esta técnica. La ML combina microburbujas y ultrasonido para fragmentar litiasis con seguridad y eficacia. Resultados in vitro y en cerdos son prometedores. Puede optimizar tratamientos y reducir niveles energéticos. Conclusiones La innovación tecnológica no solo se está aplicando a técnicas endourológicas, sino también a la ESWL. ... (AU)

ABSTRACT

La terapia de privación androgénica (TPA) es el pilar del tratamiento del cáncer de próstata hormono-sensible metastásico (CPHSm). La adición de docetaxel o de nuevas terapias hormonales (abiraterona, apalutamida o enzalutamida) mejora la supervivencia global (SG) y es en la actualidad el estándar de tratamiento. Sin embargo, la decisión sobre el régimen específico que acompañe a la TPA debe ser discutida con el paciente teniendo en cuenta factores como las posibles toxicidades asociadas, la duración del tratamiento, las comorbilidades o sus preferencias, pues no hay evidencia suficiente para recomendar un régimen sobre otro en la mayoría de los casos. En este trabajo se resume la evidencia sobre el manejo del CPHSm y se aportan recomendaciones consensuadas sobre el tratamiento óptimo para añadir a la TPA en pacientes con CPHSm con especial atención al perfil clínico del paciente (AU)


Androgen deprivation therapy (ADT) is the mainstay treatment for metastatic hormone-sensitive prostate cancer (mHSPC). The addition of docetaxel or new hormone therapies (abiraterone, apalutamide, or enzalutamide) improves overall survival and is currently the standard of care. However, the decision on the specific regimen to accompany ADT should be discussed with the patient, considering factors such as possible associated toxicities, duration of treatment, comorbidities, patient preferences, as there is no sufficient evidence to recommend one regimen over the other in most cases. This paper summarizes the evidence on the management of mHSPC and provides consensus recommendations on the optimal treatment in combination with ADT in mHSPC patients, with special attention to the patient's clinical profile (AU)

ABSTRACT

PURPOSE OF REVIEW: Urologists are at significant risk due to radiation exposure (RE) from endourological procedures for stone disease. Many techniques described have shown a reduction of RE. The purpose of this article is to review available protocols to decrease RE during such procedures and provide tips and tricks for their implementation. RECENT FINDINGS: Several low-radiation and radiation-free protocols for percutaneous nephrolithotomy and flexible ureteroscopy have been described as an attempt to reduce RE during surgery. Beginning with specific checklists to ensure adequate C-arm usage, fluoroless procedures are based on endoscopic assessment, tactile guidance, and use of ultrasound to avoid fluoroscopy. A specific preoperative checklist and low radiation or complete fluoroless radiation endourological procedures have shown to be effective, feasible, and safe. It is recommended for urologists to be aware of the risks of RE and apply the "ALARA" (As Low As Reasonably Achievable) protocols.

ABSTRACT

OBJECTIVE: To report one case of gunshot bladder trauma and to review its diagnosis and treatment in the related literature. METHODS: We report the case of a 43-year-old-male with an abdominal firearm wound and gross haematuria. Imaging diagnosis by abdominal and pelvic CT and CT-cystography. Surgical treatment. RESULTS: CT-cystography showed extraperitoneal bladder rupture. Exploratory laparotomy to evaluate for other associated injuries. Bladder wall surgical closure and ureteroneocystostomy with transvesical technique because of complete distal ureter tear. Broad spectrum antibiotherapy. Favourable progress. The patient was discharged at 14th day. CONCLUSIONS: Firearm bladder traumas are a rare entity. Surgical exploration and closure is mandatory. In haemodynamicaly stable patients, abdomen and pelvis CT and CT-cystography allow us to rule out associated injuries and to classify the bladder trauma type. Ureteral damage associated in 5-8,9%, diagnosed during surgical exploration. Broad-spectrum antibiotherapy in all patients.

ABSTRACT

OBJECTIVE: To review in the literature atypical sites of metastatic renal cell carcinoma, its onset, clinical features, diagnosis, treatment and prognosis. METHODS: To review, using Medline database, atypical sites of metastatic renal cell carcinoma in the last five years Spanish literature. RESULTS: There have been published 15 spanish articles about atypical metastatic renal cell carcinoma in the last five years. Most patients were male with a mean age of 62,3 years and methacronous metastases. Imaging and pathological diagnosis. Main sites: ocular, renal graft, larynx, suprarenal, brain, penis, gastric and pancreatic. Surgical treatment if the surgeon is able to remove the lesion. Inmunotherapy and radiotherapy in the rest of cases. CONCLUSIONS: Renal cell carcinoma represents about 3% of all adult malignancy neoplasms. Its metastatic sites, in order of frequency, are lung, bone and liver, whether synchronic or methacronic. Its location, clinical features, onset, evolution and prognosis is very variable. Individualized diagnostic and therapeutic approach, according to prognostic factors. The knowledge of this atypical sites in patients with renal cell carcinoma in the past can lead us to an earlier diagnosis and treatment which could change the evolution of the illness.

ABSTRACT

OBJECTIVE: To analyze the incidence of surgical complications its diagnosis and treatment after renal transplantation. METHODS: A retrospective study measuring the incidence of surgical complications and reviewing its diagnosis and treatment in 185 renal single transplants. RESULTS: 185 transplants, 27% had surgical complications. Only one patient lost the graft due to surgical complications and there was no associated mortality. Cold ischemia time 20 hours. Double J stenting in 19%, under surgeon's opinion. Vascular complications 3.2% (all of them renal artery stenosis). Urological complications 6.4%. Perinephric haematoma 7%. Lymphocele 4.9%. Peritoneum related complications 4%. Other 4%. The diagnosis was clinical and radiological in most of cases. 14% needed any kind of intervention. CONCLUSIONS: Our results are similar to those reported in other recent series. Only one surgical team involved and the same technique for vascular and vesico-ureteric anastomosis probably makes lower our complications rate. Early postoperative abdominal ultrasonography contributes to the diagnosis of surgical complications. The initial treatment approach is the endoscopic-conservative one, with exceptions.
