Urinary tract injury during hysterectomy:Does surgeon specialty and surgical volume matter?

BACKGROUND Ureteral injury is a known complication of hysterectomies.Recent studies have attempted to correlate surgeon volume and experience with incidence of urinary tract injuries during hysterectomies.Some studies have reported that as surgeon volume increases,urinary tract injury rates decrease.To our knowledge,no studies have assessed the relationship between surgeon subspecialty and the rate of urinary tract injury rates during minimally invasive hysterectomy.AIM To determine the incidence of urinary tract injury between urogynecologists,gynecologic oncologists,and general gynecologists.METHODS The study took place from January 1,2016 to December 1,2021 at a large comm-unity hospital in Detroit,Michigan.We conducted a retrospective chart review of adult patients who underwent minimally invasive hysterectomy.After we identified eligible patients,the surgeon subspecialty was identified and the surgeon’s volume per year was calculated.Patient demographics,medical history,physician-dictated operative reports,and all hospital visits postoperatively were reviewed.RESULTS Urologic injury occurred in four patients(2%)in the general gynecologist group,in one patient(1%)in the gynecologic oncologist group,and in one patient(1%)in the urogynecologist group.When comparing high and low-volume surgeons,there was no statistically significant difference in urinary tract injury(1%vs 2%)or bowel injury(1%vs 0%).There were more complications in the low-volume group vs the high-volume group excluding urinary tract,bowel,or major vessel injury.High-volume surgeons had four(1%)patients with a complication and low-volume surgeons had 12(4%)patients with a complication(P=0.04).CONCLUSION Our study demonstrated that there was no difference in the urinary tract injury rate in general gynecologists vs subspecialists,however our study was underpowered.

Tanshinone ⅡA improves functional recovery in spinal cord injury-induced lower urinary tract dysfunction

Tanshinone ⅡA, extracted from Salvia miltiorrhiza Bunge, exerts neuroprotective effects through its anti-inflammatory, anti-oxidative and anti-apoptotic properties. This study intravenously injected tanshinone ⅡA 20 mg/kg into rat models of spinal cord injury for 7 consecutive days. Results showed that tanshinone ⅡA could reduce the inflammation, edema as well as compensatory thickening of the bladder tissue, improve urodynamic parameters, attenuate secondary injury, and promote spinal cord regeneration. The number of hypertrophic and apoptotic dorsal root ganglion（L6–S1） cells was less after treatment with tanshinone ⅡA. The effects of tanshinone ⅡA were similar to intravenous injection of 30 mg/kg methylprednisolone. These findings suggested that tanshinone ⅡA improved functional recovery after spinal cord injury-induced lower urinary tract dysfunction by remodeling the spinal pathway involved in lower urinary tract control.

Perinephric urinoma,an unusual upper tract presentation of a lower tract injury following retroperitoneoscopy:A case report

BACKGROUND A 66-year-old lady was referred to urology for a suspected urinoma after retroperioneoscopy done for debridement of a retroperitoneal abscess that developed following a duodenal perforation.CASE SUMMARY Serous contents of the drain sent for fluid creatinine were elevated confirming this and computed tomography urography findings suggested an upper tract injury with urinoma around the kidney.However,the antegrade nephrostogram suggested otherwise and on flexible cystoscopy and cystogram,an extraperitoneal bladder perforation was instead identified,with tip of retroperitoneal drain sitting inside the bladder.CONCLUSION This case identifies a limitation in the usual diagnostic approach for such injuries and emphasizes the need to exercise caution when managing them especially when they occur after several surgical procedures and in the presence of multiple surgical drains.
