“…Subsequently, however, the landscape of urological cancer care has evolved. Namely, there have been improvements in axial abdominal imaging (CT and/or MRI), the discovery of novel urinary cancer markers, a refinement of endoscopic/ureteroscopic instrumentation and the introduction of chemotherapeutic regimens, resulting in prolonged survival for bladder cancer patients [4–7]. Collectively, these variables are likely to continue to impact disease trends and outcomes for upper‐tract urothelial neoplasms.…”

Study Type – Prognosis (retrospective cohort) Level of Evidence 2b What’s known on the subject? and What does the study add? Upper‐tract urothelial carcinoma (UTUC) is a relatively uncommon urological malignancy with survival and outcomes data largely determined from single‐centre series which can be limited by relatively small case numbers. Through review of a large population based cohort, this study provides valuable information regarding epidemiological and survival patterns for over 13,000 patients with UTUC diagnosed over the past three decades. OBJECTIVE • To evaluate epidemiological and survival patterns of upper‐tract urothelial carcinoma (UTUC) over the past 30 years through a review of a large, population‐based database. PATIENTS AND METHODS • Data from the Surveillance, Epidemiology and End Results (SEER) database from 1973 to 2005 were reviewed in 10‐year increments to evaluate disease trends. • Univariate and multivariate survival analyses identified prognostic variables for outcomes. RESULTS • In total, 13 800 SEER‐registered cases of UTUC were included. The overall incidence of UTUC increased from 1.88 to 2.06 cases per 100 000 person‐years during the period studied, with an associated increase in ureteral disease (0.69 to 0.91) and a decrease in renal pelvic cancers (1.19 to 1.15). • The proportion of in situ tumours increased from 7.2% to 31.0% (P < 0.001), whereas local tumours declined from 50.4% to 23.6% (P < 0.001). • There was no change in the proportion of patients presenting with distant disease. • In multivariate analysis, increasing patient age (P < 0.001), male gender (P < 0.001), black non‐Hispanic race (P < 0.001), bilateral UTUC (P= 0.001) and regional/distant disease (P < 0.001) were all associated with poorer survival outcomes. CONCLUSIONS • The incidence of UTUC has slowly risen over the past 30 years. • Increased use of bladder cancer surveillance regimens and improved abdominal cross‐sectional imaging may contribute to the observed stage migration towards more in situ lesions. • Although pathological disease characteristics impact cancer outcomes, certain sociodemographic factors also appear to portend worse prognosis.

“…The Storz rigid nephroscope was one of the first tools used for this purpose,[14] and since its introduction in 1965, the fiber optic rod-lens nephroscope has been the standard for percutaneous renal surgery. [15] The Olympus Invisio ® Smith digital nephroscope integrates the endoscope, digital camera, and light source in one simple “plug and play” device,[16] similar to newly introduced digital ureteroscopes. The Invisio ® weighs almost half (470 gm, 1.04 lbs) that of a standard rod-lens nephroscope (939 gm, 2.07 lbs).…”

Percutaneous nephrolithotomy (PCNL) is the procedure of choice for removing large, complex, and/or multiple renal calculi. Since its first description in 1976, PCNL techniques and equipment have evolved to maximize procedural efficacy, safety, and reproducibility. We reviewed current literature from January 2004 to November 2009 using Medline search regarding PCNL instrumentation and technology. Additional equipment discovered during the review process without published Medline evidence was summarized from manufacturer brochures and data. Included in this review are summaries of intracorporeal lithotriptors and accessory equipment, stone manipulation devices, PCNL tract sealants, and a digital rigid nephroscope. The evolution of these devices from their predecessors has increased the instrumentation options for the treating urologist and may represent more effective technology for the percutaneous treatment of large renal stones.
