Effect of obturator nerve block during transurethral resection of bladder tumors on the disease recurrence, progression and surgery outcomes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveIn our study, we aimed to evaluate the effect of the obturator nerve block (ONB) on the operation time, duration of hospital stay, complete resection, presence of muscle tissue in the pathology, second resection, recurrence, and progression, when applied in addition to spinal anesthesia in patients with primary bladder lateral wall tumor and Transurethral Resection of Bladder Tumor (TURBT) was planned. MATERIALS AND
methodsSeventy patients with bladder lateral wall tumors were included in the study. In addition, ONB was applied to 35 of the patients who underwent spinal anesthesia. The two groups were compared in terms of obturator reflex development, perforation, complete resection, presence of muscle tissue in pathology samples, need for second resection, need for second resection due to inadequate muscle tissue, and 1 year recurrence and progression rates.
resultsWhen the two groups were compared for obturator reflex and bladder perforation, both were found to be lower in the ONB group (p = 0.002, p = 0.198, respectively). The rate of complete resection and the presence of muscle tissue in the pathology samples were higher in the ONB group (p = 0.045, p = 0.034, respectively). The rates of second resection and second resection due to inadequate muscle tissue were found to be higher in the group without ONB (p = 0.015, p = 0.106, respectively). In the 1-year follow-up, the recurrence rate was significantly lower in the ONB group (p < 0.001), while there was no significant difference between the progression rates (p = 0.106).
conclusionIn our study, we found out that ONB applied in addition to spinal anesthesia increases the rate of complete and muscle tissue resection by decreasing the obturator reflex, and causes a significant reduction in the need for second resection and tumor recurrence.
