A method of treating the upper urinary tract of a mammal having a urethra extending to a bladder and a ureter extending from the bladder to a kidney. The method comprises initially extending a catheter system into the upper urinary tract, the catheter system having a urethral catheter infusion tube section extending through the urethra for infusion of a liquid; a urethral catheter drain tube section extending through the urethra for drainage of a liquid; a ureteral catheter tube section extending through a ureter into the kidney and having a first tube portion for infusion of a liquid connected to the urethral catheter infusion tube section, and a second tube portion for drainage of a liquid. The method then includes flowing a therapeutically effective liquid into the kidney through the urethral catheter infusion tube section and the ureteral catheter first, infusion tube portion, and, simultaneously with the flowing of the fluid into the kidney, draining fluid from the kidney through the urethral catheter drain tube section and the ureteral catheter second, drain tube portion.

A sleeve is provided for placing over a flexible endoscope. The sleeve has a port between its distal and proximal openings and the port is connected to a vacuum source. Once the endoscope is retracted proximal to the suction port, the sleeve's proximal opening is sealed off and the entire sleeve is turned into a suction lumen. Devices and methods in accordance with the invention provide improvement in removing materials from body cavities, especially in removing stones from the upper urinary tract.

The invention provides a decoction for treating upper urinary tract calculi. The decoction consists of lysimachia christinae hance, lygodium japonicum, endothelium corneum gigeriae galli, herba pyrrosiae, plantain seeds, talcum, lalang grass rhizome, radix paeoniae alba, root of common peony, radix cyathulae, szechwan Chinaberry fruit, rhizoma corydalis and liquorice. The decoction for treating upper urinary tract calculi disclosed by the invention can clear away heat and toxic materials, promote diuresis and diminish inflammation, resolve tetany and relieve pain, and remove calculi; the decoction is free from toxic and harmful materials as well as side effect, and has no damage to kidney; and meanwhile, the decoction can nourish and protect the kidney, and prevent recurrence of urinary tract calculi.

The invention relates to methods for locally delivering a chemotherapeutic agent to an upper tract urothelial carcinoma (UTUC). The methods involve placing a balloon catheter that has a working channel and a balloon into the ureter / renal pelvis via retrograde or antegrade ureteral access; inflating the catheter balloon to temporarily obstruct the ureter; infusing (instilling) a liposomal formulation that includes a chemotherapeutic agent into the working channel of the catheter; and allowing the infused liposomal formulation to dwell in the ureter and / or renal pelvis for a time sufficient to allow at least a portion of the liposomal formulation to adhere to the urothelial wall. In the methods of the invention, at least a portion of the infused chemotherapeutic-agent formulation adheres tothe urothelial wall while it is instilled and dwells in the ureter and / or renal pelvis. The disclosed methods can be performed as an adjuvant therapy to other methods of treating UTUC, such as ureteroscopic ablation or resection of the tumor.

The invention discloses a percutaneous flexible ureteroscopy for complex lesions of the upper urinary tract, which relates to a medical device and is used to solve the problem that the existing ureteral equipment hose is easily missed in the lower ureter, and the pump tube is easy to fall off, resulting in leakage of body fluid. question. It includes percutaneous puncture and dilation equipment, ureteroscope, cold light source, camera system, bedside B-ultrasound machine, intracavitary stone removal equipment, high-pressure balloon dilator, pressure-regulating water pump, holmium laser ureteroscope, and the ureteroscope includes The sheath tube, the hose inside the sheath tube, the push tube used to connect the sheath tube and the hose, the hand grip at the end of the sheath tube, and the cleaning valve. By rotating the combined sheath and hose, it is more suitable for complex kidney stone surgery.

Tubular prostheses are provided for use in airways, upper digestive, and urinary tracts. Each of these uses has its own specific sets of biological specifications, based on what it must contain and exclude and the physical and chemical pressures and stresses to which it is subjected. The prostheses may be made from allogeneic cells. Thus they can be manufactured and stored prior to an individual's personal need arising.

Drug delivery devices and systems, are provided for delivery of a drug into the upper urinary tract of patients in need thereof. The drug delivery devices (100) may be deployed directly into the renal pelvis via a patient's ureter, bladder, and urethra, and the drug delivery devices can be wholly retained therein for local continuous, controlled release of a drug over an extended period.

The invention belongs to the technical field of biomarkers, and discloses an upper urinary tract epithelium carcinoma (UTUC) diagnostic marker and application thereof, the upper urinary tract epithelium carcinoma diagnostic marker is DNA methylation biomarkers GDF15, TMEFF2 and VIM, the upper urinary tract epithelium carcinoma diagnostic marker is a DNA methylation biomarker, the upper urinary tract epithelium carcinoma diagnostic marker is a DNA methylation biomarker, the upper urinary tract epithelium carcinoma diagnostic marker is a DNA methylation biomarker, the upper urinary tract epithelium carcinoma diagnostic marker is a DNA methylation biomarker, and the upper urinary tract epithelium carcinoma diagnostic marker is a DNA methylation biomarker. The mRNA (messenger ribonucleic acid) sequence NM004864 of the GDF15 is shown as SEQ ID NO: 1; the mRNA (messenger ribonucleic acid) sequence NM001305134 of the TMEFF2 is as shown in SEQ ID NO: 2; the mRNA (messenger ribonucleic acid) sequence NM003380 of the VIM is shown as SEQ ID NO: 3. According to the method, the upper urinary tract epithelium cancer data are comprehensively mined from the multi-omics level, the biomarkers related to the upper urinary tract epithelium cancer are searched, the limitation of a traditional candidate gene method can be overcome, and the result accuracy is improved; clinical data are combined for integrated analysis, multiple biomarkers are jointly detected, a multi-index combined diagnosis model is established, and the diagnosis sensitivity and specificity are improved.

Problem: To provide a pharmaceutical composition for prevention or treatment of urinary track organ cancer. The composition does not cause a problem with respect to side effects, can be continually used for an extended period of time, and is administered to a urinary track organ by injection into a cavity of the urinary track organ. Solution: a solution configured to be injected into a cavity of a urinary track organ, the solution containing D-allose. The urinary track organ cavity is inside the upper urinary tract and inside the bladder. The solution is for injection therapy where the solution is injected into a cavity of a urinary track organ, and for utilization of increase in D-allose sugar intake into urinary track organ cancer cells (e.g. RT112, 253J, J82). The solution contains D-allose together with a pharmaceutically acceptable dilution agent or support. This pharmaceutical composition is for prevention or treatment of cancers in a urinary track organ.
