Cost Savings in Urology Operating Rooms by Editing Surgeon Preference Cards.

BACKGROUND AND OBJECTIVES: Operating room costs contribute significantly to the overall expenditure for inpatient care. We evaluated a simple way to reduce urology operating room costs by limiting the loss from unused disposable items. METHODS: Baseline data were collected on opened and unused disposable items. Surgeons were asked to edit their preference cards and mark optional surgical items that would only be opened if requested. RESULTS: The cost of unused disposable items during the first 4 weeks in 3 operating rooms averaged $410/week. Costs after implementing the intervention declined to an average of $30/week. This yielded $380/week in savings, equating to a 92% reduction in waste, and a potential savings of $19 760 annually in the 2 urology operating rooms alone. CONCLUSION: Since the urology department represents only 10% of the main operating rooms at our institution, if other operating rooms implemented similar cost saving methods the hospital could potentially accrue significant savings.

Anatomical study of the prostatic urethra using vinyl polysiloxane casts.

BACKGROUND: There are limited studies describing the detailed nonhistologic anatomy of the prostatic urethra. We studied radical prostatectomy specimens to describe the ex vivo anatomical details of its shape and size. METHODS: We conducted an observational study examining the prostatic urethra anatomy. Prostatic urethra casts (molds) were made using vinyl polysiloxane immediately after fresh specimens had been retrieved following prostatectomy for organ-confined prostate cancer. The following measurements were taken from the casts: anterior length, posterior length, maximal diameter, bladder neck to verumontanum, verumontanum to apex length, and prostate urethral angle (PUA). Prostate volume was calculated using the ellipsoid formula: ((p/6) × transverse × length × height). RESULTS: Thirty-three prostatic urethral casts were obtained. The mean prostate volume was 38.59 cc. The mean PUA was 127.6°. The mean transverse, apex, and length of the prostate were 4.65, 4.06, and 3.63 cm, respectively. The mean distance from the verumontanum to sphincter was 1.2 cm. The ratio between the anterior and posterior length of the prostatic urethra was 0.82 cm and did not correlate with prostatic size (Figure 8). CONCLUSION: The distance from the verumontanum to the apex does not change with prostate size; it is uniform with a mean length of 1.2 cm. The anterior length, posterior length, and maximum diameter of the prostatic urethra increase with prostate size. The mean difference between the anterior and posterior length is 0.8 cm and did not correlate with prostate size. Urethral angulation decreased with prostate size but was not significant. Information obtained from this study is of value designing prostatic stents and devices for benign prostatic hyperplasia.

Native kidney cytomegalovirus nephritis and cytomegalovirus prostatitis in a kidney transplant recipient.

We present a case of cytomegalovirus (CMV) native kidney nephritis and prostatitis in a CMV D+/R- kidney transplant recipient who had completed six months of CMV prophylaxis four weeks prior to the diagnosis of genitourinary CMV disease. The patient had a history of benign prostatic hypertrophy and urinary retention that required self-catheterization to relieve high post-voiding residual volumes. At 7 months post-transplant, he was found to have a urinary tract infection, moderate hydronephrosis of the transplanted kidney, and severe hydroureteronephrosis of the native left kidney and ureter, and underwent native left nephrectomy and transurethral resection of the prostate. Histopathologic examination of kidney and prostate tissue revealed CMV inclusions consistent with invasive CMV disease. This case highlights that CMV may extend beyond the kidney allograft to involve other parts of the genitourinary tract, including the native kidneys and prostate. Furthermore, we highlight the tissue-specific risk factors that preceded CMV tissue invasion. In addition to concurrent diagnoses, health care providers should have a low threshold for considering late-onset CMV disease in high-risk solid organ transplant recipients presenting with signs and symptoms of genitourinary tract pathology.

Readmission Rate and Causes at 90-Day after Radical Cystectomy in Patients on Early Recovery after Surgery Protocol.

Background: Radical cystectomy (RC) is associated with high risk of early and late perioperative complications, and readmissions. The Enhanced Recovery After Surgery (ERAS) protocol has been applied to RC showing decreased hospital stay without increased morbidity. Objective: To evaluate the specific causes of hospital readmissions in RC patients treated before and after adoption of an ERAS protocol at our institution. Methods: We retrospectively evaluated the outcome of 207 RC patients on ERAS protocol at the Stanford University Hospital from January 2012 to December 2014. We focused on early (30-day) and late (90-day) postoperative readmission rate and causes. Results were compared with a pre-ERAS consecutive series of 177 RC patients from January 2009 to December 2011. Results: In the post-ERAS time period a total of 56 patients were readmitted, 41 within the first 30 days after surgery (20%) and 15 within the following 60 days (7%). Fever, often associated with dehydration, was the most common reason for presentation to the hospital, accounting for 57% of all readmissions. At 90 days infection accounted for 53% of readmissions. Of all the patients readmitted during the first 90 days after surgery, 32 had positive urine cultures, mostly caused by Enterococcus faecalis isolated in 18 (56%). Readmission rates did not increase since the introduction of the ERAS protocol, with an incidence of 27% in the post-ERAS group versus 30% in the pre-ERAS group. Conclusions: Despite accurate adherence to most recent perioperative antibiotic guidelines, the incidence of readmissions after RC due to infection still remains significant.

Diagnosis and Surgical Management of Uroenteric Fistula.

Uroenteric fistulae can occur between any part of the urinary tract and the small and large bowel. Classification is generally based on the organ of origin in the urinary tract and the termination of the fistula in the segment of the gastrointestinal tract. Surgery is often necessary. Congenital fistulae are rare, with most being acquired. Uroenteric fistulae most frequently occur in a setting of inflammatory bowel disease. Imaging often helps in the diagnosis. Management of urinary fistulae includes adequate nutrition, diversion of the urinary tract, diversion of the gastrointestinal tract, treatment of underling inflammatory process or malignancy, and surgery.

Surgical outcomes and complications associated with presurgical tyrosine kinase inhibition for advanced renal cell carcinoma (RCC).

BACKGROUND: Tyrosine kinase inhibitors (TKI) have dramatically changed the management paradigm of advanced renal cell carcinoma (RCC) and are increasingly being used preoperatively to achieve cytoreduction. OBJECTIVE: To review our case series of post-TKI surgical procedures to add to the current perioperative efficacy and complication profile. MATERIALS AND METHODS: Between October 2006 and February 2010, 14 cytoreductive nephrectomies, radical nephrectomies, and metastectomies were performed after neoadjuvant sunitinib or sorafenib for advanced RCC. During the same time frame, a control group of 73 consecutive patients underwent radical nephrectomy, cytoreductive nephrectomy, or metastectomy in the absence of prior systemic therapy. We compared the incidence of perioperative complications and outcomes after surgical procedures between the two cohorts. RESULTS: Median preoperative renal mass size was 11 cm (6.7-24.2 cm). Primary tumor shrinkage was seen in 57%; median shrinkage was 18% (8%-25%). The median treatment period was 17 weeks, and the median time from TKI discontinuation was 2 weeks. Compared with a control group and after adjusting for confounding covariates, presurgical TKI use was not associated with a significant increase in perioperative complications (50% vs. 40%, P = 0.25) or perioperative bleeding (36% vs. 34%, P = 0.97) but was associated with increased incidence and grade of intraoperative adhesions (86% vs. 58%, P = 0.001; grade 3 vs. 1, P = 0.002). CONCLUSIONS: Compared with the published reports, we observed less hemorrhagic and wound healing issues but a significant increase in incidence and severity of intraoperative adhesions, which can present a formidable technical challenge. Potential reasons for our lower complication rate could be increased time from TKI discontinuation to surgery, longer time to postoperative TKI re-initiation, increased use of preoperative angioembolization, and the lack of preoperative bevacizumab administration. Presurgical TKI therapy can permit effective surgical cytoreduction with a safety and complication profile equivalent to that of non-TKI-nephrectomy; however safety data continue to evolve, and preoperative TKI use requires further prospective investigation.

Safety and feasibility of the prostatic urethral lift: a novel, minimally invasive treatment for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).

OBJECTIVES: • To investigate the Prostatic Urethral Lift (PUL) procedure, a novel, minimally invasive treatment for symptomatic benign prostatic hyperplasia (BPH), which aims to mechanically open the prostatic urethra without ablation or resection. • To demonstrate the safety and feasibility of this procedure and to make an initial assessment of effectiveness. PATIENTS AND METHODS: • The PULprocedure was performed on 19 men in Australia. • Small suture-based implants were implanted transurethrally under cystoscopic visualisation to separate encroaching lateral prostatic lobes. • Patients were evaluated at 2 weeks and 3, 6, and 12 months after PUL. RESULTS: • All cases were successfully completed with no serious or unexpected adverse events (AEs). • Between two and five sutures were delivered in each patient and the prostatic urethral lumen was visually increased in all patients. • Reported postoperative AEs were typically mild and transient and included dysuria and haematuria. • Follow-up cystoscopy at 6 months in a subset of patients showed no calcification. Histological findings from two of three patients who progressed to transurethral resection of the prostate for return of symptoms showed no evidence of inflammation related to the implanted materials. • The mean International Prostate Symptom Score was reduced by 37% at 2 weeks and 39% at 1 year after PUL as compared with baseline. CONCLUSIONS: • We demonstrated in this initial experience that the PUL procedure is safe and feasible. • The safety profile of the PUL procedure appears favourable; most patients reported sustained symptom relief to 12 months with minimal morbidity • PUL therefore warrants further study as a new option for the many patients who seek an alternative to current therapies.

Gender differences in radical cystectomy: complications and blood loss.

OBJECTIVES: To review the impact of gender on blood loss, transfusions, and complications. Radical cystectomy is technically different between men and women. Unique to women, dissection of the anterior vaginal wall can be associated with added blood loss. METHODS: We analyzed the records of 262 consecutive patients who underwent radical cystectomy for urothelial carcinoma from March 1993 to March 2003. The perioperative variables, amount of blood loss, transfusion requirements, need for intensive care, length of hospitalization, and 30-day complications were examined. RESULTS: Women accounted for 24% (n = 63) of this series and had a median operative blood loss of 1.4 L compared with 0.5 L in men (P = 0.001). The transfusion rate was 82% in women and 55% in men (P = 0.001), with the median number of units transfused greater in women (3 U versus 2 U, P = 0.043). Also, 31% of women needed intensive care compared with 15% of men (P = 0.004). The median postoperative stay was similar at 9 days for women and 8 days for men (P = 0.099). The incidence of complications was not significantly different statistically between the gender groups, occurring in 43% of women and 33% of men (P = 0.161). Major complications occurred in 8% of women and 7.5% of men, and the most common minor complication was ileus, reported in 19% of women and 14% of men. CONCLUSIONS: Although the overall complications and length of hospital stay were similar between the gender groups, radical cystectomy in women was associated with greater blood loss, transfusion requirements, and intensive care needs.
