Efficacy and Safety of Obturator Nerve Block in Transurethral Resection of Bladder Tumors: A Comprehensive Review.
Review in Cureus, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Transurethral resection of bladder tumors (TURBT) is a pivotal procedure in the management of bladder cancer, essential for both diagnosis and treatment. Effective anesthesia is crucial in TURBT to ensure a stable and pain-free operative field, facilitate precise tumor resection, and minimize complications such as the obturator reflex, which can lead to involuntary leg movement and bladder injury. The obturator nerve block (ONB) is a regional anesthesia technique designed to prevent the obturator reflex by blocking the obturator nerve, which innervates the adductor muscles of the thigh. This comprehensive review evaluates the efficacy and safety of ONB in TURBT. It begins by discussing the anatomical and physiological aspects of the obturator nerve, followed by a detailed examination of various ONB techniques, including ultrasound-guided and landmark-based methods. The review assesses the impact of ONB on pain management, reduction of adductor muscle spasms, and overall improvement in surgical conditions and patient satisfaction. Additionally, it explores the incidence and types of complications associated with ONB, such as hematoma, nerve injury, and local anesthetic systemic toxicity (LAST). It compares ONB with other anesthesia techniques used in TURBT, such as general, spinal, and epidural anesthesia. A critical analysis of key clinical studies and meta-analyses is presented to provide a comprehensive understanding of the current evidence on ONB efficacy and safety. Future directions and innovations in ONB techniques, including advances in imaging and nerve localization, are also discussed. Practical recommendations for implementing ONB in clinical practice, including guidelines for clinician training and patient selection criteria, are provided. This review aims to inform clinicians about the benefits and risks of ONB in TURBT, guide clinical practice, and identify areas for future research to optimize anesthesia management in bladder cancer surgery.
