Open versus robot-assisted laparoscopic ureteral reimplantation: Hospital charges analysis and outcomes at a single institution.

PURPOSE: Robot-assisted laparoscopic extravesical ureteral reimplantation has previously been described as a viable minimally invasive option to open surgery. However, concerns for robotic surgery have been raised owing to assumed higher costs and heterogeneous clinical outcomes. We hypothesized that similar hospital charges and clinical outcomes occur when comparing open and robotic cases in matched cohorts. MATERIALS AND METHODS: Open and robotic reimplantation cases from 2013 to 2015 for primary vesicoureteral reflux were matched by age using 1:1 nearest neighbor matching. The matched cohorts were analyzed and compared for their direct itemized hospital charges per surgical case, complications, and clinical outcomes. RESULTS: There were 38 patients in each group after age-matching the 135 patients. Operating room charges were higher for the robotic group compared to the open group (p=0.002), whereas pharmacy and laboratory costs were lower for the robotic group. However, there were no significant differences in total overall charges between the open and robotic groups with cystoscopy or without cystoscopy (p=0.345, p=0.533), since the median hospital stay length was shorter for the robotic group (p<0.001). Clinical success rates were identical for the two groups (open 94.8% vs robotic 94.8%). There were also no significant differences in number of complications between the two cohorts. CONCLUSIONS: This is the first age-matched study comparing hospital charges and clinical outcomes of pediatric open and robotic reimplantation. While operating room charges were higher for the robotic cohort, lower hospitalization charges led to comparable overall hospital charges, as well as equivalent clinical outcomes for both cohorts. LEVEL OF STUDY: Level III (Retrospective comparative study) TYPE OF STUDY: Retrospective Study.

Urologic Outcomes of Children With Hemorrhagic Cystitis After Bone Marrow Transplant at a Single Institution.

OBJECTIVE: To analyze clinical outcomes and the risk factors associated with genitourinary (GU) morbidity and mortality in children who present with hemorrhagic cystitis (HC) after bone marrow transplant (BMT). METHODS: A retrospective chart review of patients with HC who had undergone BMT at a single pediatric hospital from 2008 to 2015 was conducted. Demographic data, severity of hematuria, HC management, and mortality were analyzed. Bivariate analysis and binary logistic regression were performed to identify risk factors. RESULTS: Out of 43 patients who met inclusion criteria, 67.4% were male with a median age at BMT of 10.2 years (interquartile range 5.8-14.6). Percutaneous nephrostomy catheters were inserted in 5 patients for urinary diversion. All-cause mortality was 32.6% (N = 14). Intravesical retroviral therapy (P <.001), HC grade (P <.001), total Foley time (P <.001), total gross hematuria time (P <.001), total days hospitalized (P = .012), and days to most improved hematuria (P = .032) were associated with significant GU morbidity on bivariate analysis. On multivariable analysis, days to most improved hematuria was associated with significant GU morbidity odds ratio of 1.177 (1.006-1.376) (P = .042). Status of percutaneous nephrostomy was not associated with increased mortality (P = .472); however, in the multivariate model, BK viremia (P = .023), need for renal dialysis (P = .003), and presence of Foley catheter (P = .005) were associated with increased mortality. CONCLUSION: Children with HC after BMT fall in a very high-risk category with high mortality and significant GU morbidity. The presence of a Foley catheter, need for dialysis, and BK viremia are associated with increased mortality.

Vacuum-assisted Closure of a Vesicocutaneous Fistula in a Pediatric Patient After Bladder Cystoplasty.

A vesicocutaneous fistula is an abnormal communication from the bladder to the skin (Pritts et al, 2001). Recently, wound vacuum-assisted closure (VAC) has been used to facilitate fistula closure. There are no reports of using VAC to help fistula closure in the pediatric population. We present a case of an adolescent patient who develops a vesicocutaneous fistula after bladder augment cystoplasty and was treated with VAC only.
