Purpose: To register all cases of urothelial cancer and renal cell carcinoma (RCC) in Norway during 1999–2018 to obtain the contemporary incidence of UTUC and UTUC incidence relative to other urothelial cancers and RCC. Further to analyse possible changes over time regarding UTUC incidence, UTUC patient characteristics, tumour characteristics and survival. Methods: 3502 cases registered with ICD code C65 and C66 during 1999–2018 at the Norwegian cancer registry were entered into a database. After a selection process 3096 cases were included in the study. The crude incidences of UTUC were calculated for each year adjusting for the corresponding population data. Age-standardized rates adjusting to the European standard population (2013) were calculated. Comparisons were made with other cases of urothelial cancer and RCC. For changes over time, the material was split into 5-year periods. Regression analysis was used to calculate yearly changes and for assessing statistical significance. Survival outcomes were calculated using the Kaplan–Meier method. Results: The overall age-standardized incidence rate was 3.88, increasing from 3.21 to 4.70 from first to last 5-year periods. The increase affected all ages except those < 60 years of age, and were observed regardless of gender or anatomical location. UTUC constituted 11.8% of all urothelial cancers, increasing from 9.9 to 12.8%. Mean patient age at diagnosis increased from 71.5 to 73.4 years. The 5-years Cancer-specific survival improved from 57.4 to 65.4%. Conclusion: The incidence of UTUC was higher than expected and increasing. Patient age at diagnosis was increasing.
Objective: To perform an up‐to‐date review to scope the current status of the thulium fibre laser (TFL) in the setting of stone lithotripsy and provide a guide for the clinical urologist. Methods: A review of world literature was performed to identify original articles on TFL for stone lithotripsy. Our clinical experiences of using the technology have also been shared. Results: To date there have been 11 clinical studies published on TFL for stone lithotripsy. Three of these have been in the setting of miniaturised percutaneous nephrolithotomy (mini‐PCNL) and the remainder have been on ureteroscopy (URS). There has only been one randomised study on this technology, which has been for URS. For URS, the range of settings has been 0.1–4 J × 7–300 Hz for both URS and mini‐PCNL. Stones ranging from 0.4–3.2 and 1.5–3 cm have been treated with URS and mini‐PCNL, respectively. The final stone‐free rate for TFL has ranged from 66.6% to 100% and 85–100% for URS and mini‐PCNL, respectively. The average length of stay ranged from 0.5 to 2.4 days in the URS group, but no studies have been reported this for mini‐PCNL. Operative times in all the studies (both URS and mini PCNL) were <60 min. Conclusion: Initial clinical studies reveal that TFL appears to be efficacious in the setting of stone lithotripsy. However, further randomised trials are warranted to delineate its formal position, as well as determine the optimal settings for use in clinical practice.

To look for an increase in the incidental detection of renal cell carcinoma (RCC) over the last two decades and to see if different patterns of healthcare use for men and women have implications for tumour detection and survival. We present an historical series of 368 consecutive patients treated with nephrectomy for RCC during the period 1978-2000. The patients were classified according to detection mode (incidental or symptomatic disease), TNM stage and cancer-related death. The frequency of incidentally detected RCC (IRCC) increased from 21.1% to 34.7% between the first and second decades of the study. The IRCC group had significantly more low-stage (I-II) tumours (p = 0.002), a smaller tumour size (p < 0.0001) at operation and significantly better cancer-specific survival (p = 0.0048) than the symptomatic renal cell carcinoma (SRCC) group. The frequency of women was significantly higher in the IRCC group than in the SRCC group (p = 0.02). Females had significantly more low-stage (I-II) tumours (p = 0.02) and better cancer-specific survival (p = 0.05) than males. The number of incidentally discovered renal tumours is increasing. IRCC have lower TNM-stage and are smaller than SRCC. IRCC have better long term cancer specific survival than SRCC. The better survival rate found in females may be due to more extensive use of the healthcare system by females than males.
