Urology treats urinary tract diseases in all genders and male reproductive issues, covering the kidneys, bladder, prostate, urethra, from infections to complex cancers.

The success of minimally invasive urology depends on accurate, detailed diagnosis. Before a patient enters the operating theater at Liv Hospital, they undergo a comprehensive diagnostic evaluation designed to map the anatomy, characterize the pathology, and determine the optimal surgical approach. Unlike open surgery, where a surgeon can make a large incision to “explore,” minimally invasive surgery requires precise preoperative planning. The surgeon must know precisely where the tumor is, how many blood vessels supply the organ, and the exact location of critical structures like the ureters and nerves. This phase utilizes state-of-the-art imaging and biopsy techniques to create a virtual roadmap for the robotic or laparoscopic procedure.
Imaging is a key part of diagnosing urological problems today. It lets the surgical team see inside the body with great detail.
Endoscopy lets the urologist see inside the urinary tract with high-definition cameras, giving a clear view without needing to make any cuts.
For suspected malignancies, tissue diagnosis is often required before definitive surgery.
Understanding how the urinary system is functioning is just as important as knowing what it looks like, especially when reconstructive surgery is planned.
Renal Scintigraphy (Renogram): This nuclear medicine test evaluates the function of each kidney independently. It helps determine whether a kidney blocked by a stone or tumor is still functioning or has lost function and requires removal. It is also used to assess the severity of blockages in conditions like ureteropelvic junction obstruction.
After collecting all the information, the Liv Hospital team uses it to plan the minimally invasive surgery. Before robotic surgery, the surgeon reviews 3D images to prepare for the procedure. They look for any unusual features, like extra arteries or different ureter positions, that could affect the surgery. This careful planning is important for safety and efficiency. The diagnostic phase also helps decide if minimally invasive surgery is suitable, especially for patients with complex anatomy or advanced disease.

A standard prostate biopsy usually involves taking random samples from the prostate, which can miss small tumors located in difficult-to-reach areas. A fusion biopsy overlays the MRI images (which show precisely where the suspicious area is) onto the live ultrasound image, allowing the doctor to guide the needle directly into the target with extreme precision.
Cystoscopy is generally performed under local anesthesia (numbing gel) for men and women, or sometimes light sedation. While it can be uncomfortable and create an urge to urinate, it is usually not painful. The flexible scopes used today are very thin and navigate the anatomy gently. The procedure typically takes only a few minutes.
Contrast dye is injected into the veins to highlight the blood vessels and the urinary tract. The kidneys filter this dye and excrete it into the urine. This allows the CT scan to clearly show the relationship between a tumor and the blood vessels and to outline the inner shape of the kidney and ureter, which are impossible to see without contrast.
Imaging can provide a very high probability, but it is rarely 100 percent definitive. For example, a solid mass in the kidney that enhances with contrast is treated as cancer until proven otherwise, often leading to surgery without a prior biopsy. However, for prostate and bladder issues, a tissue biopsy is almost always required to confirm the diagnosis and determine the aggressiveness of the cells.
The decision is often based on the complexity revealed by the tests. If the tumor is in a difficult position that requires intricate reconstruction and suturing (such as a partial nephrectomy where the kidney must be sewn back together), the robot is often preferred for its dexterity. For simpler removal procedures, standard laparoscopy may be sufficient. The imaging helps guide this choice.
