Endo-Urological Techniques for Benign Uretero-Ileal Strictures Have Poor Efficacy and Affect Renal Function.

INTRODUCTION: Uretero-ileal strictures (UES) following urinary diversion are therapeutically challenging. We compared the efficacy, safety and renal outcome following therapeutic endo-urological techniques (EUTs) and open surgical revision of the anastomosis (SRA) for UES. MATERIAL AND METHODS: We retrospectively analysed all EUTs and SRAs performed for UES in 2 hospitals between 1987 and 2015. Restenosis was defined as recurrent radiographically diagnosed hydronephrosis and re-intervention. Renal function (estimated glomerular filtration rate [eGFR]) decrease was correlated with the number of EUTs per patient. RESULTS: Eighty-five UES were treated with 105 EUTs and 31 open revisions. Due to total obstruction, 28 (27%) EUTs were aborted. During a median follow-up of 33 months, restenosis occurred following 53 out of 77 (69%) completed EUTs and 4 out of 31 (13%) SRAs (p < 0.001 on univariable and multivariable analyses). No serious (Clavien ≥3b) EUT-related complications occurred vs. 5 (19%) related to SRA (p < 0.001). The number of finalised EUTs was independently associated with eGFR loss (ß = 12.3 mL/min/1.73 m2 loss per EUT, p = 0.008), with a significant cutoff value of >1 EUTs. SRA did not affect renal function (ß = 6.8 mL/min/1.73 m2 loss, p = 0.276). CONCLUSIONS: Although EUTs are less invasive, they have an inferior efficacy to SRA. Our results suggest that a maximum of one EUT may be attempted without significantly compromising renal function.

Primary urethral carcinoma in females: an epidemiologic study on demographical factors, histological types, tumour stage and survival.

PURPOSE: To obtain insight into demographical factors, histology and survival rates of females diagnosed with primary urethral cancer and to determine favourable treatment. METHODS: Data from 91 females with primary urethral carcinoma, age varying from 15 to 85 years, registered between 1989 and 2008 at the National Cancer Registry of the Netherlands were used for this study. Demographical factors, incidence rate, morphology and tumour stage according to TNM classification were analysed. Kaplan-Meier survival curves were constructed and stratified by stage, histological type and treatment modality. RESULTS: The overall crude annual incidence was 0.7 per million women with a peak incidence in the age group of 80-84 years. Analysis of the morphology showed urothelial cell carcinoma (UCC) in 45 %, squamous cell carcinoma (SCC) in 19 %, adenocarcinoma (AC) in 29 %, and unknown or undifferentiated carcinoma accounted for 6 %. Almost half of patients (46 %) had advanced disease at time of diagnosis and was mainly treated with surgery and/or radiotherapy. The 5-year survival rates of stage 0-II, stage III and stage IV were 67, 53 and 17 %, respectively. The 5-year survival rates of SCC, UCC and AC were 64, 61 and 31 %, respectively. CONCLUSIONS: Female primary urethral carcinoma is a rare condition, and the majority of patients were aged above 65 years. Almost half of patients have advanced disease upon diagnosis. TNM stage and histological type of disease are the most determining factors for survival. Extended surgery with or without radiotherapy seems to be the most favourable treatment. Awareness and early diagnosis are important to improve survival.

The international prostate symptom score overestimates nocturia assessed by frequency-volume charts.

PURPOSE: We analyzed differences in nocturia, as estimated by the International Prostate Symptom Score and 7-day frequency-volume charts. MATERIALS AND METHODS: A total of 398 forms were collected from 500 consecutive urological outpatients willing to record a 7-day frequency-volume chart. All patients completed a general questionnaire, an International Prostate Symptom Score, and a bladder symptom and bother score. Missed recordings were indicated by a coded letter. Patients who lacked essential data, bedtimes or an International Prostate Symptom Score, or who recorded the frequency-volume chart for less than 5 days were excluded from study. RESULTS: A total of 186 men and 115 women with a mean age of 56 years were evaluable. In 10.6% of patients no nocturia occurred. Of those with nocturia 70% and 34% experienced nocturia a mean of 1 or more and 2 or more times, respectively. In 43% of patients the International Prostate Symptom Score equaled calculated categorized nocturia while 50% had a higher International Prostate Symptom Score nocturia score than calculated nocturia. On univariate analysis the correlation of International Prostate Symptom Score question 7 with mean nocturia increased with frequency-volume chart duration (day 1 r = 0.52 to day 3 r = 0.63). On longer duration frequency-volume charts the correlation showed no further increase. Multivariate regression analysis revealed that the nocturia score was determined by mean nocturia in the frequency-volume chart, the nocturia bother score and patient age. CONCLUSIONS: The International Prostate Symptom Score nocturia score overestimated nocturia in most patients, as derived from a 7-day frequency-volume chart. When scoring International Prostate Symptom Score nocturia question 7, patients included a degree of bother. The correlation of question 7 with mean nocturia increased with frequency-volume chart duration until day 3.

A cross-sectional study of the international prostate symptom scores related to age and gender in Dutch adults reporting no voiding complaints.

OBJECTIVE: To determine the IPSS in a selected population reporting no voiding complaints. SUBJECTS AND METHODS: 1143 adults without voiding complaints were included. They were divided over both sexes and all decades. All subjects filled out questionnaires including the IPSS. Statistical analysis was aimed at relating the IPSS to age and gender. RESULTS: The IPSS in both sexes shows a gradual significant increase in consecutive age groups. Men in the third age decade have a mean score of 2.8, while men older than 70 years of age have a score of 7.0. In women these scores are 4.0 and 5.6 respectively. The increase is about equally caused by storage and voiding scores. The items addressing weak stream in men and nocturia and urgency in men and women are the major factors causing the correlation with age. Nearly 17% of all subjects have moderate symptom scores and 1% has severe scores. CONCLUSION: In both adult men and women reporting no voiding complaints the IPSS increases with age. This rise is more prominent in males.
