Impact of Diagnostic Ureteroscopy on Intravesical Recurrence and Survival in Patients With Urothelial Carcinoma of the Upper Urinary Tract

Diagnostic Ureteroscopy Prior to Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma Increased the Risk of Intravesical Recurrence

“…The general descriptions of included studies were summarised in Table 1. Among the included studies, 7 (60%) were from Asian countries [8, 10, 11, 13, 14, 17] and 3 studies were conducted in USA [9, 15, 16] and one in France [12], respectively. A total of 4,057 participants were included in the subsequent meta-analysis, of which 518 patients had a history of TCC in bladder.…”

“…Eight studies [8-11, 13, 14, 17, 24] provided HRs for the URS-related risk of IVR, including 3,340 participants, of which 1,219 had IVR. The reasons to exclude the other 3 studies from quantitative analysis included no HR available [16] and HRs were for URS-related risk of recurrence (both upper tract and IVR) [12, 15].…”

Kidney-sparing Management Versus Nephroureterectomy for Upper Tract Urothelial Carcinoma: a Systematic Review and Meta-analysis

“…Additionally, laparoscopic nephroureterectomy, extravesical bladder cuff resection and positive surgical margin were also the predictors. Previous ureteroscopy seemed to be an independent intravesical recurrence risk factor (Luo et al, 2013), but it's still controversial (Ishikawa et al, 2010;Gurbuz et al, 2011;Nison et al, 2013). Tumor grade was another impact factor of oncologic outcome.…”

Diagnostics clinique, urétéroscopique et photodynamique des tumeurs de la voie excrétrice urinaire supérieures : état-de-l’art pour le rapport scientifique annuel de l’Association française d’urologie

“…L'hypothèse d'un possible essaimage tumoral induit par l'hyperpression dans les cavités rénales au décours de l'urétéroscopie n'a finalement jamais été confirmée [27]. L'impact sur la récidive vésicale par contact avec le liquide d'irrigation reste débattu [28][29][30]. L'augmentation du délai de prise en charge induit par l'exploration endoscopique couplée aux biopsies n'affecterait pas de manière significative le devenir oncologique [17].…”
