Vi.5 gives the vitiating causes for thirteen srotas across verses 10 to 22, and mutravaha is the eleventh of the thirteen, at verse 20, between sukravaha at 19 and varcovaha at 21. ### Suśruta Saṃhitā Śārīra Sthāna 9:11–12 (Bhishagratna); cited as 9/12 elsewhere, checked against the source > The two urine carrying Srotas (channels) have their roots in the bladder and the penis (urethra). An injury to any of these is marked by constipation or epistaxis in the bladder, retention of urine, and numbness of the genitals. tr. Kaviraj Kunja Lal Bhishagratna (1911) · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-3-sharirasthana/d/doc142889.html Suśruta's root = bladder + penis/urethra, against Caraka's bladder + groins. 'constipation or epistaxis in the bladder' is Bhishagratna's own odd English and should be flagged, not relied on. ## Not to be confused with - **basti.** basti is the bladder (the root organ) and also the name of the enema therapy, a standing ambiguity in Ayurvedic English. - **vaṅkṣaṇa.** Caraka's second root; rendered 'groin' by WHO but read as the ureters/inguinal region by others. It is not the same as Suśruta's śepha. - **udakavaha srotas.** Modern writers map udakavaha to 'fluid balance' and then to renal function; the texts keep water homeostasis (palate/kloma) separate from urine (bladder/groin). - **medovaha srotas.** vṛkka (kidney) is the root of MEDOVAHA in Caraka, not of mūtravaha, the most counter-intuitive fact in the whole srotas scheme and a constant source of error. ## Renderings that do not hold - the renal system / kidneys. Neither text names the kidney as a root of this channel. In Caraka the kidneys (vṛkka) are the root of the FAT channel. Rendering mūtravaha srotas as 'kidneys' silently rewrites the text. - 'constipation or epistaxis in the bladder'. Bhishagratna's phrasing is garbled English for obstruction/haemorrhage; quoting it as a clinical sign misrepresents both the Sanskrit and the translator. - vaṅkṣaṇa = ureters. A plausible modern reading but not what WHO ('groin') or the Sanskrit says; presenting it as settled is unwarranted. ## Open questions Recorded rather than resolved. - What is vaṅkṣaṇa anatomically, inguinal region, ureters, or both? - Why does Caraka place the kidneys under medovaha rather than mūtravaha? Is this a physiological claim about perirenal fat or a different vṛkka? ## Citation Age Ayurveda Nighantu, "mūtravaha srotas", https://nighantu.ageayurveda.com/lexicon/mutravaha-srotas/, CC BY 4.0.
