Assessment of association between lower ureteric excision technique and oncological outcomes for upper urinary tract urothelial carcinoma: retrospective analysis from the Scottish Renal Cancer Consortium.

PURPOSE: Nephroureterectomy(NU) remains the gold-standard surgical option for the management of upper urinary tract urothelial carcinoma(UTUC). Controversy exists regarding the optimal excision technique of the lower ureter. We sought to compare post-UTUC bladder tumour recurrence across the Scottish Renal Cancer Consortium(SRCC). METHODS: Patients who underwent NU for UTUC across the SRCC 2012-2019 were identified. The impact of lower-end surgical technique along with T-stage, N-stage, tumour location and focality, positive surgical margin, pre-NU ureteroscopy, upper-end technique and adjuvant mitomycin C administration were assessed by Kaplan-Meier and Cox-regression. The primary outcome was intra-vesical recurrence-free survival (B-RFS). RESULTS: In 402 patients, the median follow-up was 29 months. The lower ureter was managed by open transvesical excision in 90 individuals, transurethral and laparoscopic dissection in 76, laparoscopic or open extra-vesical excision in 31 and 42 respectively, and transurethral dissection and pluck in 163. 114(28.4%) patients had a bladder recurrence during follow-up. There was no difference in B-RFS between lower-end techniques by Kaplan-Meier (p = 0.94). When all factors were taken into account by adjusted Cox-regression, preceding ureteroscopy (HR 2.65, p = 0.001), lower ureteric tumour location (HR 2.16, p = 0.02), previous bladder cancer (HR 1.75, p = 0.01) and male gender (HR 1.61, p = 0.03) were associated with B-RFS. CONCLUSION: These data suggest in appropriately selected patients, lower ureteric management technique does not affect B-RFS. Along with lower ureteric tumour location, male gender and previous bladder cancer, preceding ureteroscopy was associated with a higher recurrence rate following NU, and the indication for this should be carefully considered.

Pediatric Renal Angiomyolipomas in Tuberous Sclerosis Complex.

PURPOSE: Tuberous sclerosis complex is a genetic disorder characterized by the growth of hamartomas in multiple organs. Up to 80% of patients with tuberous sclerosis complex will have at least 1 angiomyolipoma in their lifetime. We describe the incidence and natural history of angiomyolipoma in a pediatric tuberous sclerosis complex population and analyze tumor growth to determine optimal renal imaging intervals in an effort to improve counseling, treatment and followup. MATERIALS AND METHODS: We performed a retrospective chart review of all patients with tuberous sclerosis complex from 2004 to 2014. Patients were included if they had a clinical or genetic diagnosis of tuberous sclerosis complex and had undergone at least 1 renal imaging study. RESULTS: A total of 145 patients were analyzed. Median age was 14 years (range 0 to 28). Overall incidence of angiomyolipoma was 50.3%. Median age at first angiomyolipoma detection was 11 years (range 2 to 26). Median yearly angiomyolipoma growth rate stratified by age at first detection was 0.0 mm for patients 0 to 6 years old, 0.9 mm for those 7 to 11 years old, 2.5 mm for those 12 to 16 years old and 1.8 mm for those 17 years old or older. Median yearly angiomyolipoma growth rate stratified by tumor size at first detection was 0.1 mm for tumors 0.6 to 0.9 cm, 1.8 mm for those 1.0 to 1.9 cm and 4.3 mm for those 2.0 to 2.9 cm. A total of 35 patients (24.1%) received mTOR (mammalian target of rapamycin) inhibitors. Eight patients underwent a total of 13 surgical interventions, of whom 2 had previously been treated with mTOR inhibitors. Median patient age at surgical intervention was 18.0 years and median angiomyolipoma size was 5.0 cm. CONCLUSIONS: Angiomyolipoma growth in children with tuberous sclerosis complex can be rapid and unpredictable. We recommend yearly renal ultrasound in all patients with tuberous sclerosis complex, with consideration of magnetic resonance imaging in those at risk for rapid growth and future intervention (ie those older than 11 years and/or those with renal angiomyolipomas larger than 2 cm).

A Study of Adolescent Female Genitalia: What is Normal?

STUDY OBJECTIVE: Female adolescents often present to health care providers with concerns about the appearance of their external genitalia. These patients might experience significant distress about their genital appearance and might request surgery to correct a perceived abnormality. Accurate descriptions of normal adolescent female genital anatomy are lacking in the literature. The purpose of this study was to examine a small sample of normal female adolescents to obtain measurements and descriptors of the external genital structures, with a focus on the size and morphology of the labia minora. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: Participants were female adolescent patients, ages 10-19 years, who underwent routine surgical procedures in the operating room. RESULTS: Forty-four patients were examined. The mean age was 14.4 years (range 10-19 years). Mean height was 159.6 cm and mean weight was 60.8 kg. Most were non-Hispanic ethnicity (n = 32/44; 72%) and were Caucasian race (n = 38/44; 86%). Right and left labia minora lengths were different in n = 19/44 patients (43%). Right and left labia minora widths also differed, in stretched (n = 20/33; 61%) and unstretched (n = 24/44; 55%) labia, with a difference ranging from 1 to 22 mm. There was no correlation between size and shape of labia minora and patient age, height, weight, or race. CONCLUSION: Wide variability exists in female adolescent genital anatomy with no established normal range. This study provides a resource for physicians who care for adolescent girls, who need normative data to describe female genital anatomy. We propose that the role of labiaplasty in adolescents should be considered with extreme caution because of the wide range in size and morphology and paucity of data in this population.

Adolescent testicular microlithiasis: A case-based, multinational survey of clinical management practices.

INTRODUCTION: Testicular microlithiasis (TM) is a condition characterized by calcium deposits within the testis, usually detected incidentally during ultrasonography of the scrotum. TM has been associated with the presence of, and possibly the development of, testicular malignancy. Our aim was to document international clinical management practices for TM and to analyze what factors and perception of risk influence conservative versus active management and follow-up. METHODS: European Society for Paediatric Urology (ESPU) and Society for Pediatric Urology (SPU) members were invited to complete an online case-based survey of clinical management practices of TM. Eight cases had a single variable changed each time (classic versus limited TM, unilateral versus bilateral, prior cryptorchidism versus no cryptorchidism) to ascertain the provider's perception of risk. The respondents completed multiple choice questions on initial management, follow-up plan, length and interval of follow-up. Multivariate logistic regression was performed to determine factors associated with decisions on management and follow-up. RESULTS: There were 265 respondents to the survey from 35 countries (Table). Median time in practice was 13 years. Factors that were significantly associated with more aggressive initial management (more than counseling on self-examination) included: not yet in independent practice, low volume TM cases per year, those practicing pediatric and adult urology, classic appearance of TM and cryptorchidism. Factors that were significantly associated with urologist follow-up and active investigation included: European practitioners, low TM case volume per year, those practicing both pediatric urology and pediatric surgery, classic TM appearance and a case history of cryptorchidism. Interval and length of follow-up was wide-ranging, with most respondents favoring annual follow-up. CONCLUSION: Management of TM varies and a mix of surgeon and case factors significantly influences management strategies. This baseline understanding of the lack of systematic management suggests the need for the development of consensus guidelines and prospective study.

Comparative Outcomes and Perioperative Complications of Robotic Vs Open Cystoplasty and Complex Reconstructions.

OBJECTIVE: To compare perioperative and surgical outcomes in a 2-center, 2-surgeon open vs robotic augmentation ileocystoplasty. MATERIALS AND METHODS: We reviewed patients undergoing augmentation ileocystoplasty open vs robotically between 2008 and 2014 at 2 centers. We compared the groups' preoperative characteristics, perioperative outcomes, complications, and interim functional outcomes. RESULTS: The cohort consisted of 17 and 15 patients with median follow-up of 45 and 46 months, in open and robotic groups, respectively. Median operative time (incision to closure) was longer in the robotic cohort (265 minutes vs 623 minutes, P < .001). Median length of stay (7 days vs 6 days, P = .335), time to diet (4 days vs 4 days, P = .125), and mean intravenous morphine equivalents/kg (1.23 mg/kg vs 0.56 mg/kg, P = .091) were comparable between groups for open and robotic, respectively. There were 4/17 (23.5%) of the open cohort who had an epidural for an average of 93 hours. All patients had stable or improved hydronephrosis postoperatively. Major reoperations, such as for bowel obstruction, were required in 2/17 (11.7%) in the open group and none in the robotic cohort. Minor stomal complications requiring skin-level revision or endoscopic procedure occurred in 4/17 (23.5%) in the robotic cohort and 2 (11.7%) in the open group. CONCLUSION: We reveal equivalent rates of complications, length of stay, and blood loss for augmentation cystoplasty among appropriately matched controls. Prolonged operative times of the robotic cohort did not lead to additional morbidity for patients. Further steps to reduce morbidity and additional investigations should be undertaken prior to widespread adoption of the intracorporeal technique in experienced robotic centers.
