Ultrasound-Guided Ilioinguinal/Iliohypogastric Block Mitigates Catheter-Related Bladder Discomfort After Prostate Surgery: A Prospective Randomized Controlled Trial.

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
Background Catheter-related bladder discomfort (CRBD) is a common and distressing complication of transurethral resection of the prostate (TURP), especially in elderly patients. However, effective prevention strategies are lacking. This study aimed to evaluate the efficacy of ultrasound-guided iliohypogastric-ilioinguinal nerve block (IINB) in alleviating CRBD. Methods Eighty elderly male patients who underwent TURP were randomly assigned to the IINB group (n = 40), which received bilateral iliosubcostal-ilioinguinal nerve blocks after general anesthesia with 15 ml of 0.33% ropivacaine on each side, or the control group (n=40), which received only standard general anesthesia. The primary outcome was the severity of CRBD (rated on a 0-3 scale) at 5 min, 1 h, 3 h, 6 h, 12 h, and 24 h postoperatively. Secondary outcomes included postoperative pain visual analog scale (VAS) scores, intraoperative opioid consumption, post-anesthesia care unit (PACU) stay duration, and other postoperative complications. Results This study evaluated the impact of nerve block (Group N) versus control (Group C) on CRBD, pain scores, opioid consumption, and recovery parameters in patients undergoing TURP. Group N exhibited significantly lower CRBD scores at 5 min (p<0.001), 1 h (p<0.001), 3 h (p<0.001), and 6 h (p<0.05) postoperatively, with no differences at 12 h or 24 h. Similarly, VAS pain scores were reduced in Group N at all early timepoints (5 min to 6 h; p<0.05 to p<0.001), aligning with the CRBD findings. Intraoperatively, Group N required less sufentanil (26.25 ± 5.63 μg vs. 32.88 ± 6.29 μg; p<0.001) and remifentanil (170.45 ± 53.63 μg vs. 217.88 ± 67.79 μg; p=0.001), and demonstrated a shorter extubation time (6.83 ± 1.75 min vs. 8.13 ± 1.49 min; p=0.001). PACU stay duration did not differ significantly (p=0.309). The incidence of postoperative complications, including postoperative nausea and vomiting (PONV), chills, hypoxemia, and sinus bradycardia, showed no statistically significant differences between groups (all p>0.05), as analyzed by Fisher's exact test.
