Retroperitoneal Causes of Genitourinary Pain Syndromes: Systematic Approach to Evaluation and Management.

INTRODUCTION: Women with pelvic pain commonly report pain in their ovaries, vagina, uterus, or bladder. These symptoms may be caused by visceral genitourinary pain syndromes but also may be caused by musculoskeletal disorders of the abdomen and pelvis. Understanding neuroanatomical and musculoskeletal factors that may contribute to genitourinary pain is important for evaluation and management. OBJECTIVES: This review aims to (i) highlight the importance of clinical knowledge of pelvic neuroanatomy and sensory dermatomal distribution of the lower abdomen, pelvis, and lower extremities, exemplified in a clinical case; (ii) review common neuropathic and musculoskeletal causes of acute and chronic pelvic pain that may be challenging to diagnose and manage; and (iii) discuss female genitourinary pain syndromes with a focus on retroperitoneal causes and treatment options. METHODS: A comprehensive review of the literature was performed by searching the PubMed, Ovid Embase, MEDLINE, and Scopus databases using the keywords "chronic pelvic pain," "neuropathy," "neuropathic pain," "retroperitoneal schwannoma," "pudendal neuralgia," and "entrapment syndromes." RESULTS: Retroperitoneal causes of genitourinary pain syndromes have substantial overlap with common conditions treated in a primary care setting. Thus, a comprehensive and systematic history and physical examination, with focused attention to the pelvic neuroanatomy, is key to establishing the correct diagnosis. In the clinical case, such a comprehensive approach led to the unexpected finding of a large retroperitoneal schwannoma. This case highlights the intricacy of pelvic pain syndromes and the complex nature of their possible overlapping causes, which ultimately affects treatment planning. CONCLUSION: Knowledge of the neuroanatomy and neurodermatomes of the abdomen and pelvis, in addition to understanding pain pathophysiology, is critical when evaluating patients with pelvic pain. Failure to apply proper evaluation and implement proper multidisciplinary management strategies contributes to unnecessary patient distress, decreased quality of life, and increased use of health care services.

The Endogenous Opioid System: Role and Dysfunction Caused by Opioid Therapy.

The endogenous opioid system is comprised of a wide array of receptors and ligands that are present throughout the central and peripheral nervous system, the gastrointestinal tract, and the immune system. This explains the multitude of physiological functions it is responsible for including analgesia, mood regulation, and modulation of the stress response. It also plays a pivotal role in modulating the brain's reward center with behavioral and social implications on mood disorders and addiction. Exogenous opioid therapy hijacks the endogenous system and alters its functions contributing to an imbalance that is responsible for the pathogenesis of several disease states.

The K-Technique: A Novel Technique for Laparoscopic Apical Suspension Using Barbed Sutures.

OBJECTIVES: Hysterectomy is among the most common gynecologic procedures performed for women, second only to cesarean sections, and the proportion of it performed laparoscopically continues to increase. Addressing apical support at the time of the hysterectomy is crucial to minimizing the risk of posthysterectomy prolapse. Barriers to addressing apical support include the lack of experience in laparoscopic suturing and knot tying that require advanced skills and dexterity. The K-technique is a novel modification of the uterosacral ligament suspension procedure using the knot-less barbed suture technology, rendering suturing easier and quicker to perform. METHOD: The vaginal cuff epithelium is closed with 2 unidirectional barbed sutures that are started at the lateral fornices and ran until the midsection. The same sutures will then serially purchase the anterior and posterior vaginal endopelvic fascia and the midsegment of the uterosacral ligament. Two more passes are thrown through the same structures, yet farther laterally, back and forth. A video illustration of the procedure is attached. RESULTS: Eighteen patients underwent the procedure with no urinary tract injuries documented by cystoscopy and no postoperative morbidity documented during the 6-week postoperative follow-up period. Limited short- and long-term follow-up data are reassuring, but more will be needed to confirm the efficacy of barbed sutures in prolapse repair. CONCLUSIONS: The K-technique combines the conventional uterosacral ligament suspension concept with the ease, effectiveness, and safety of barbed sutures. The technique might aid the surgeon to add the apical vaginal support when indicated.
