Medical uroscope machine

Urological Endoscopy is the "gold standard" for the diagnosis and treatment of urinary system diseases, achieving non-invasive exploration, accurate diagnosis and minimally invasive treatment through natural cavities or tiny incisions. The following is a comprehensive analysis from six dimensions:

1. Technical principles and equipment evolution

Core components

Optical system: 4K ultra-high-definition/3D imaging, NBI narrow-band light for early identification of tumors

Scope type:

▸ Hard scope (0°-70° viewing angle, used for bladder/ureter)

▸ Soft scope (270° bending, reaching the renal pelvis)

Working channel: supports laser fiber, stone basket, biopsy forceps and other instruments

Technology iteration

From fiberscope to electronic scope: pixel increase 100 times (now up to 500,000 pixels)

From white light to intelligent imaging: fluorescent markers (such as 5-ALA) make cancer cells "self-luminous"

2. Full spectrum of clinical applications

Disease field Diagnostic application Therapeutic application

Bladder Tumor staging, interstitial cystitis evaluation Tumor resection (TURBT), lithotripsy

Ureter Stricture positioning, foreign body detection Stent placement, laser lithotripsy

Kidney Hematuria tracing, space-occupying lesion biopsy Percutaneous nephrolithotomy (PCNL)

Prostate hyperplasia assessment and enucleation (HoLEP)

III. Comparison of mainstream devices

Type Diameter Advantages Classic scenarios

Cystoscopy 16-22Fr Large channel and multi-instrument collaboration Prostate resection

Ureteroscopy 7.5-9.9Fr Active bending 270° Laser powderization of renal pelvic stones

Percutaneous nephroscope 18-30Fr Direct establishment of renal channel Staghorn stone removal

Disposable electronic scope 6.5Fr Zero risk of cross infection Outpatient rapid examination

IV. Essentials of surgical procedures (taking ureteroscopic lithotripsy as an example)

Preoperative

Three-dimensional CT planning of stone location, general anesthesia

Intraoperative

Insert soft endoscope under the guidance of guidewire, and holmium laser "eats away" stones to <2mm

Place double J tube to prevent stenosis if necessary

Postoperative

Drink 2000ml of water on the same day, and remove the catheter in 3 days

V. Complication prevention and control

Bleeding: plasma bipolar electrocoagulation

Infection: preoperative urine culture + targeted antibiotics

Perforation: real-time pressure monitoring during surgery (<40cmH₂O)

VI. Five major breakthrough directions in the future

AI real-time pathology: automatic distinction between low-grade and high-grade urothelial carcinoma under the microscope

Microrobot: magnetically controlled capsule endoscope to screen early lesions

Virtual reality training: doctors simulate surgery on 3D reconstructed organs

Biodegradable stents: no need for secondary removal after surgery

Targeted photodynamic therapy: accurate elimination of in situ cancer cells

Industry value summary

Uroscopic technology enables urology to achieve:

🔹 Diagnosis upgrade: early tumor detection rate increased by 3 times

🔹 Treatment innovation: 90% of stone surgeries do not require surgery

🔹 Patient benefits: hospital stay shortened to 1-2 days

With the integration of single-port laparoscope and endoscope, the future will usher in a new era of "scarless surgery".
