Tissue integration of polyacrylamide hydrogel: An experimental study of periurethral, perivesical
, and mammary gland tissue in the pig.
The defect length was much longer in this patient due to elevation of the bladder neck by a perivesical
hematoma, which developed during the trauma and subsequently became fibrosed.
The invasive urothelial carcinomas (n = 10) invaded the lamina propria (n = 5; 50%), muscularis propria (n = 4; 40%; Figure, D), and perivesical
soft tissue (n = 1; 1%).
Vesical involvement includes superficial or deep tissue layers and adjacent perivesical
soft tissue (14).
Invasion into the perivesical
fat may be revealed as infiltration or irregular fat-bladder wall interface.
Computed tomography (CT) showed a mass with hyperdense components that invaded perivesical
fat about 10 cm diameter.
Blunt dissection was carried down to the perivesical
Anterior pelvic tumours that require dissection near the bladder neck are problematic because of the perivesical
venous plexus that often bleeds heavily or continuously.
CT scan of abdomen and pelvis showed local infiltration of the perivesical
area with small retroperitoneal adenopathy.
Then connect it in a three-corner fashion to the vaginal mucosa and the break in the perivesical
tissue along the bladder.
Endoscopic techniques may involve resecting the ureteric orifice down to perivesical
fat or transurethrally incising around the ureteric orifice and occluding the free orifice with an Endoloop (Ethicon, Cincinnati, OH).
20) Based on Table 1, muscularis propria infiltration is common (about 60% of the whole patient population), whereas perivesical
soft tissue invasion is not frequent (about 5% of the cases, without any apparent difference between IMT and PMP).
