Purpose To compare surgery outcomes and safety of button bipolar enucleation of the prostate vs laparoscopic simple prostatectomy in patients with large prostates (> 80 g) in a two-center cohort study. Methods All patients with lower urinary tract symptoms due to benign prostatic enlargement (Prostate volume > 80 cc) undergoing button bipolar enucleation of the prostate (BTUEP) or laparoscopic simple prostatectomy (LSP) in two centers were enrolled. Data on clinical history, physical examination, urinary symptoms, uroflowmetry and prostate volume were collected at 0, 1, 3 6, 12, 24 and 36 months. Early and long-term complications were recorded. Results Overall, 296 patients were enrolled. Out of them, 167/296 (56%) performed a LSP and 129/296 (44%) performed a BTUEP. In terms of efficacy both procedures showed durable results at three years with a reintervention rate of 8% in the LSP group and of 5% in the BTUEP group. In terms of safety, BTUEP and LSP presented similar safety profiles with a 9% of transfusion rate and no major complications. Conclusion LSP and BTUEP are safe and effective in treating large-volume adenomas with durable results at three years when performed in experienced centers.

Ureteral hernias through the inguinal duct are uncommon. There are 2 types: paraperitoneal and extraperitoneal. The most common is the paraperitoneal (80%) which is accompanied by hernia sac and can appear with other abdominal organs. The extraperitoneal often accompanied by retroperitoneal fat. Both types of hernias are usually indirect. Treatment is usually herniorrhaphy.

Lymphocele is a common pathology after a renal transplantation, which needs to be treated depending on its clinical manifestations. There are mainly two therapeutic alternatives, depending on the size of the lymphocele: sclerotherapy and surgical intraperitoneal drainage. Apart from highly selected cases, laparoscopic approach is currently considered first choice when a surgical treatment is prescribed due to its security and effectiveness.

Resumen.-OBJETIVOS: Presentar nuestra experiencia con cuatro casos de quistes de las glándulas de Skene de gran tamaño, realizar una revisión de la literatura publicada y conocer así los distintos diagnósticos diferenciales y el manejo a seguir. MÉTODOS: Cuatro mujeres remitidas a nosotros desde su ginecólogo por presentar masas parauretrales refractarias a tratamiento conservador con posible afectación de la uretra distal. CONCLUSIONES: El quiste de la glándula de Skene es una patología que raramente tratan los urólogos debido a su escasa repercusión clínica pero cuando nos es remitida por los ginecólogos es importante realizar un estudio completo del aparato urinario para realizar así un diagnóstico diferencial certero que excluya patologías malignas o alte-
