Sub-gluteal ligation of the internal pudendal vein for management of veno-occlusive erectile dysfunction (Shaeer's Vein Ligation-I): the cadaveric study.

Vein ligation for veno-occlusive erectile dysfunction is being abandoned due to the recurrence rate. Among the reasons for failure is inability to ligate the deep system of veins; the internal pudendal vein. The vein exits the pelvis in the gluteal region, from the lesser sciatic foramen to the greater sciatic foramen, coursing over the ischial spine and sacro-spinous ligament, under the gluteus maximus. This work aims to verify feasibility of the first surgical procedure to ligate the internal pudendal vein through the gluteal approach. This cadaveric study involved five formalin-fixed cadavers. A surface anatomical landmark was designed to identify the ischial spine, at the intersection of two lines: a vertical line from posterior superior iliac spine to ischial tuberosity, and a horizontal line extending from sacro-coccygeal joint, laterally. An incision is cut encompassing the target point. Subcutaneous fat is dissected down to the gluteus maximus, which is split along the direction of its fibers. The vein can be found crossing over the ischial spine. "Shaeer's Vein Ligation - I" appears to be surgically feasible. A protocol for a surgical study is registered at clinicaltrials.gov, and is open for participation.

Intrasurgical Seminiferous Tubular Diameter Correlates with Total Motile Sperm Count in Azoospermia: a Prospective Cohort Study.

We aimed to find a correlation between the intraoperative diameters of the seminiferous tubules evaluated at high magnification during micro-testicular sperm extraction (micro-TESE) and total motile sperm count (TMSC) in non-obstructive azoospermic (NOA) patients. Five hundred four consecutive NOA patients were included and underwent micro-TESE. The change in the mean TMSC and different seminiferous tubular diameters was of high statistical significance (p < 0.001). It should be noted that the highest mean TMSC was reported in the dilated tubules (DTs) group followed by the other study groups 941.72 ± 196.97, 487.37 ± 443.57, and 34.54 ± 60.79, respectively. Furthermore, 21 naïve cases had dilated tubules (DTs) and 18 (85.7%) of them had shown eventful micro-TESE. Conversely, 186 naïve cases had slightly dilated tubules (SDTs), and 101 (54.3%) of them had eventful micro-TESE. Only 8 (24.25%) cases of the 33 cases had non dilated tubules (NDTs) and showed eventful micro-TESE. The frequency of intrasurgical seminiferous tubular diameter and micro-TESE outcome among the naïve cases had demonstrated a highly statistical significance (p < 0.001). Interestingly, all salvaged cases (100%) with DTs and a previous eventful TESE had shown eventful TESE in the current study. The most dilated intrasurgical seminiferous tubular diameter is associated with the highest TMSC in NOA patients including SCO cases.

A shot to the heart: a rare case of cardiac embolization.

SummaryThis is a case report of intracardiac foreign bodies that gained access to the heart by migration from a peripheral vein. The case report describes the diagnostic findings on cardiac imaging and summarizes different approaches to management. LEARNING POINTS: Appearance of embolized cardiac missiles with reverberation and acoustic shadowing.Role of different imaging modalities in the diagnosis of intracardiac foreign bodies.Indications for surgical or transcatheter retrieval.
