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.
Another consequence of this procedure is an increased risk of kidney infections due to bacteria from faeces travelling back up the ureters (reflux). Patients are commonly put on oral prophylactic antibiotics to combat infections in the ureteral tract and kidneys, but this can lead to tolerance of the antibiotic.
The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
A partial nephrectomy should be attempted when there is a kidney tumor in a solitary kidney, when there are kidney tumors in both kidneys, or when removing the entire kidney could result in kidney failure and the need for dialysis. Partial nephrectomy is also the standard of care for nearly all patients with small renal masses (<4 cm in size). [22]
Risks during surgery include heart problems, pulmonary (lung) complications, development of blood clots , blocking of arteries , and injury to adjacent structures, such as bowel or vascular entities. Inadequate ureteral length may also be encountered, leading to ureteral kinking and subsequent obstruction.
Nephropexy is the surgical intervention aiming to reposition and fixate a floating or mobile kidney. [1] This is done in order to prevent its descent ( nephroptosis ) or to deliberately move the kidney downward in order to compensate for a shortened ureter . [ 1 ]
This is the joining site of the ureters and the section of intestine used for the diversion. The ureteroenteric anastomosis can be created in a number of different ways. There is the option of a refluxing or a non-refluxing type, and the two ureters can be joined into the intestinal segment either together or separately.
Transurethral surgery has been the cornerstone of endourology. Most of the urinary tract can be reached via the urethra, enabling prostate surgery, surgery of tumors of the urothelium, stone surgery, and simple urethral and ureteral procedures. Recently, the addition of laparoscopy and robotics has further subdivided this branch of urology.
