Ureterolysis is a surgical procedure aimed at exposing the ureter in order to free it from external pressure or adhesions or to avoid injury to it during pelvic surgery, most often hysterectomy. References
Pyeloplasty is a type of surgical procedure performed to treat an uretero-pelvic junction obstruction if residual renal function is adequate. [1]This revision of the renal pelvis treats the obstruction by excising the stenotic area of the renal pelvis or uretero-pelvic junction and creating a more capacious conduit using the tissue of the remaining ureter and renal pelvis.
Ideally, the patient will have undergone urethrography to visualize the positioning and length of the defect. The normal pre-surgical testing/screening (per the policies of the admitting hospital, anesthesiologist, and urological surgeon) will be performed, and the patient will be advised to ingest nothing by mouth, "NPO", for a predetermined period of time (usually 8 to 12 hours) prior to the ...
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
Ureteroscopy is an examination of the upper urinary tract, usually performed with a ureteroscope that is passed through the urethra and the bladder, and then directly into the ureter. [1]
Ureteroureterostomies are often performed because of injured or scarred ureters, especially when the ureter in question is damaged in its upper third section. [2] Generally if the patient has distal uretral strictures (narrowing of the ureter), [3] a ureteroureterostomy is not recommended and a ureter reimplantation would be favorable.
Becker then found that regeneration could be improved by applying electricity at the wound when there was a negative potential outside the amputation stub. He also found that bone has piezoelectric properties which would cause an application of force to generate a healing current, which stimulated growth at stress locations in accordance with ...
In bone surgery, a corticotomy is a cutting of the bone that may or may not split it into two pieces (bone fracture) but involves only the cortex, leaving intact the medullary vessels and periosteum. Corticotomy is particularly important in distraction osteogenesis or surgically facilitated orthodontic therapy.
