Abstract: The present disclosure discloses systems and methods for measuring the bladder volume of a patient. An ultrasound transducer array may be used to transmit electrical pulses and receive the backscattered pulses that can be analyzed to develop a representation of the patients bladder. The backscattered ultrasound signals may be amplified, converted, and processed by circuitry and computer software to develop an axial position of the anterior and posterior bladder walls. Bladder volume measurements derived from the patients bladder may then be wirelessly transmitted to a display device for assessment by a healthcare provider. The ultrasound transducer array portion of the device may be held in place between the patients peritoneum and pubis by an elastic strap or a belt to ensure proper positioning.

Abstract: The present invention discloses systems and methods for use in the treatment and management of obstructive urolithiasis. A coupling device between a nephrostomy tube and external fluid and control connections may be used in some embodiments of the present invention. This coupling device may provide a quick connection between the nephrostomy tube and a reservoir for irrigation and a collection container for drainage of the kidney. In some embodiments, a triple lumen nephrostomy tube may be used to house an irrigation catheter for irrigation of the patient's kidneys and a ureteral modulation wire and enable drainage of fluid from the kidneys. The ureteral modulation wire may be inserted into the patient's ureter through the kidney in conjunction with the nephrostomy tube. A harness system is also disclosed that may be used in conjunction with the coupling device and the triple lumen nephrostomy tube to enable a patient to independently control irrigation and drainage of the kidney.
