1. An indwelling transurethral bladder catheter having reduced trauma risk, the catheter comprising:
a proximal end, a distal end, and a flexible elongate tubular body therebetween, the distal end having at least one distal port in fluid communication with a lumen extending within the elongate tubular body, the distal end further having a distal tip comprising a blunt shape;
a first proximal port for at least one of fluid inflow or outflow, the first proximal port in fluid communication with the lumen extending within the elongate tubular body;
an inflatable balloon near the distal end of the catheter, the balloon transformable from an unexpanded to an expanded configuration,
wherein the balloon in its expanded configuration comprises a low profile oblong shape suitable for anchoring within a human bladder and providing a seal proximate an internal urethral orifice, the low profile oblong shape comprising a first dimension in a radial direction that is at least about 1.5× of a second dimension in an axial direction, and
wherein the balloon is sized and positioned sufficiently close to a distal tip of the distal end of the catheter to enable a cystoscope protruding from the distal tip to view ureter openings of the bladder, the balloon positioned such that an axial length from a distal end of the balloon in its expanded configuration to the distal tip of the distal end of the catheter is no greater than ⅕ of an axial length from a proximal end of the balloon in its expanded configuration to the distal tip of the distal end of the catheter, wherein a proximal most edge of the balloon in its expanded configuration is aligned with a point at which the balloon attaches to the elongate tubular body, the distal end of the catheter extending distally beyond the distal end of the balloon and into the bladder in an axial direction, wherein the balloon and the distal end of the catheter are coupled distinct elements;
a second proximal port for balloon inflation, in fluid connection with the balloon; and
a third proximal port for insertion of a cystoscope therethrough, the third proximal port being fluidly connected to the lumen extending within the elongate tubular body.
