Conceptual Study of Mutravaha Srotomula with Modern Insights

Background: Ayurveda describes Purusha as Srotomaya, emphasizing the role of Srotas in maintaining the balance of Dosha, Dhatu, and Mala. Among them, Mutravaha Srotas holds special importance as the proper elimination of urine is vital for metabolism. Ancient Acharyas have explained Mutravaha Srotomula differently: Sushruta identified Basti (urinary bladder) and Medra (urethra), while Charaka and Vagbhata considered Basti and Vankshana (groin). Such variations highlight the need to clarify both the anatomical and functional perspectives of Srotas. Aim and Objectives: This study aims to revisit and analyze the concept of Mutravaha Srotomula as explained in Ayurvedic classics, and to correlate it with modern anatomical and physiological perspectives for better understanding of urinary functions and disorders. Materials and Methods: A comprehensive review of Ayurvedic texts including Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, along with their commentaries, was undertaken. Supplementary references were gathered from modern anatomical literature, published research, and online databases to establish conceptual and clinical correlations. Results and Discussion: Basti is recognized as the principal site for urine collection and a central location for manifestations of Srotodushti such as Atipravritti (excessive flow) and Sanga (retention). Clinical conditions like cystitis, overflow incontinence, and bladder rupture align with these descriptions. Vankshana, corresponding to the inguinal region, emerges as a site where referred pain, lymphadenopathy, and related urinary pathologies manifest. Medra, representing the urethra, serves as the passage and expression site, with disorders such as strictures, BPH, and trauma validating its role. Conclusion: The Ayurvedic delineation of Mutravaha Srotomula demonstrates remarkable correlation with modern anatomy of the bladder, groin, and urethra. This integrated understanding provides a comprehensive framework for interpreting urinary physiology, pathogenesis, and clinical management from both Ayurvedic and contemporary perspectives.
