Grade I (haematoma)
Grade - Contusion or Haematoma. Grade II (laceration)
(laceration - Less than 50% transection. Grade III (laceration)
(laceration) - Greater than 50% transection. Grade IV (laceration)
Grade - Complete transection with
2 cm of devascularization. Grade V (laceration)
(laceration) - Avulsion with greater than
2 cm of devascularization.
cm Type of Ureteral injuries
Crushing by misapplication of the clamps
Ligation with a suture
Transection ( Partial / complete)
Angulation of the ureter with secondary
Ischaemia from ureteral stripping electrocoagulation.
Resection of a segment of ureter.
Combination of the above. Incidence of surgical injury
Gynecologic surgery 50 – 66 %
General / Colorectal Surgery 15 – 25 %
Abdominal vascular surgery 5 – 10 %
Ureteroscopy (perforation) 1% - 5 % Sites of ureteral injuries
usually involves the lower third
Ovarian vascular pedicle at
Ureteric relation with the
Cardinal ligament, where the
ureter crosses under the
Cardinal ligament tunnel,
dorsal to the infundibulo
-pelvic ligament near or at
the pelvic brim.
Lateral rectal pedicles.
Pathological distortion of the
ureteral Treatment depends on
Immediate - intra-op diagnosis.
- after few days to weeks. If diagnosed intra-op
PCN If diagnosed intra-op
Grade 3,4,5:(depending on the level of injury)
Short segment loss:
– Open or Lap. Ureteric reimplantation.
– Open or Lap. Uretero-ureterostomy.
– Open or Lap. Psoas hitch. Long segment loss:
– Open or Lap. Boari flap.
– Open or Lap. Ileal ureter. Mode of presentation
Can present post operatively
- Obstructive uropathy.
Endo balloon dilatation.
(using Ho:YAG Laser).
(using Post-op. period
Per-cutaneous drainage of the urinoma (if needed)
Wait for edema, induration to settle down.
Ante grade nephrostogram, 6 weeks later.
Definitive repair on a later date.
(depends on the type of ureteral injury).
(depends Newer developments
Endoscopic Laser luminization
Laparoscopic ileal ureter.
Lap SIS replacement of ureter. References
