Modified laparoscopic intravesical nonrefluxing ureteral reimplantation with psoas hitch using a submucosal tunneling

The Japanese Urological Association's clinical practice guidelines for urotrauma 2023

The Japanese Urological Association's guidelines for the treatment of renal trauma were published in 2016. In conjunction with its revision, herein, we present the new guidelines for overall urotrauma. Its purpose is to provide standard diagnostic and treatment recommendations for urotrauma, including iatrogenic trauma, to preserve organ function and minimize complications and fatality. The guidelines committee comprised urologists with experience in urotrauma care, selected by the Trauma and Emergency Medicine Subcommittee of the Specialty Area Committee of the Japanese Urological Association, and specialists recommended by the Japanese Association for the Surgery of Trauma and the Japanese Society of Interventional Radiology. The guidelines committee established the domains of renal and ureteral, bladder, urethral, and genital trauma, and determined the lead person for each domain. A total of 30 clinical questions (CQs) were established for all domains; 15 for renal and ureteral trauma and five each for the other domains. An extensive literature search was conducted for studies published between January 1, 1983 and July 16, 2020, based on the preset keywords for each CQ. Since only few randomized controlled trials or meta-analyses were found on urotrauma clinical practice, conducting a systematic review and summarizing the evidence proved challenging; hence, the grade of recommendation was determined according to the 2007 "Minds Handbook for Clinical Practice Guidelines" based on a consensus reached by the guidelines committee. We hope that these guidelines will be useful for clinicians in their daily practice, especially those involved in urotrauma care.

Laparoscopic ureteroureterostomy with an intraoperative retrograde ureteroscopy-assisted technique for distal ureteral injury secondary to gynecological surgery: a retrospective comparison with laparoscopic ureteroneocystostomy

OBJECTIVES

The aim of this study was to compare the operative and postoperative outcomes of laparoscopic ureteroureterostomy (LAP-UU) using a retrograde ureteroscopy-assisted technique with laparoscopic ureteroneocystostomy (LAP-UNC) in treating ureteral injury after gynecological surgery.

MATERIALS AND METHODS

The study analyzed 60 ureteral injury repairs performed between May 2010 and February 2016 in patients who underwent either LAP-UU using the retrograde ureteroscopy-assisted technique (n = 26) or LAP-UNC (n = 34). Demographic parameters, operative variables and perioperative outcomes were retrospectively analyzed. The chi-squared test, Fisher's exact test and Student's t test were used for statistical analyses.

RESULTS

Demographic and clinical data revealed no significant differences between patients in each group in terms of age, body mass index, length of obstruction, incidence of postoperative urinary leakage, incidence of urinary tract infection during hospitalization, oral antibiotics, mean hospital stay, incidence of recurrent obstruction, rate of conversion to open surgery and mean operative time. The LAP-UU group had significantly less estimated blood loss (85 ± 40 vs 120 ± 35 ml, p = .0006) and a significantly lower incidence of vesicoureteral reflux (grade I) on cystography (0/26 vs 6/34, p = .031) during a mean follow-up of 36.5 months (range 7-71 months).

CONCLUSIONS

Compared with LAP-UNC, LAP-UU is also a technically feasible and safe option for repairing distal ureteral injury secondary to gynecological surgery. The intraoperative retrograde ureteroscopy-assisted technique during LAP-UU contributes to precise localization of the lesion, reduces intraoperative bleeding, enables sufficient dissection of the intramural ureter and preserves its natural antireflux mechanism.
