Others present with pain, blood in the urine, recurrent infections or abnormalities detected during imaging investigations.
Dr Paul Manohar provides comprehensive assessment and management of kidney and ureter conditions, including advanced minimally invasive and robotic surgical techniques where appropriate. His goal is to provide personalised, evidence-based care that preserves kidney function while achieving the best possible outcomes for each patient.
Dr Manohar provides expert diagnosis and treatment for a wide range of kidney and ureter conditions, including kidney cancer, kidney stones, urinary tract obstruction and congenital abnormalities.
Using advanced diagnostic techniques and minimally invasive treatment options where appropriate, he works closely with patients to achieve the best possible outcomes while preserving kidney function.
Explore the conditions below to learn more about symptoms, causes and available treatment options.
Kidney cancer is one of the most common cancers affecting the urinary system. It often develops silently and may be discovered incidentally during imaging performed for unrelated reasons.
Symptoms may include:
Not all kidney tumours are cancerous, making accurate diagnosis and assessment essential.
Treatment depends on factors such as tumour size, location, stage and overall patient health. Management options may include active surveillance, partial nephrectomy, radical nephrectomy or other specialised treatments.
Dr Manohar has extensive experience in minimally invasive and robotic surgery and can provide expert advice regarding the most appropriate treatment pathway for individual patients.
Kidney stones are among the most common conditions treated by urologists. They develop when minerals within the urine crystallise and form solid deposits within the kidney.
Some stones remain within the kidney without causing symptoms, while others can move into the urinary tract and lead to severe pain or obstruction.
Common symptoms include:
Treatment depends on the size, location and composition of the stone. Small stones may pass naturally, while larger stones may require intervention.
Dr Manohar offers comprehensive management of kidney stone disease, including both acute treatment and strategies to reduce the risk of future stone formation.
Ureteric stones occur when a kidney stone moves from the kidney into the ureter, the tube that carries urine from the kidney to the bladder.
These stones can partially or completely block urine flow and frequently cause intense pain.
Symptoms may include:
Management depends on the size and location of the stone, the degree of obstruction and the patient’s symptoms.
Treatment options may include observation, medical therapy, ureteroscopy and laser stone treatment or other procedures depending on the clinical situation.
Kidney obstruction occurs when urine cannot drain normally from the kidney. This can result in swelling of the kidney, known as hydronephrosis, and may eventually affect kidney function if left untreated.
Causes may include:
Some patients experience pain or recurrent infections, while others have no symptoms and are diagnosed following imaging studies.
Prompt assessment is important to identify the underlying cause and prevent long-term damage to the kidney.
UPJ obstruction is a narrowing where the kidney joins the ureter, restricting the normal flow of urine from the kidney.
This condition may be present from birth or develop later in life. It can result in hydronephrosis, pain, recurrent infections and progressive impairment of kidney function.
Symptoms may include:
Some patients are diagnosed following investigations performed for unrelated reasons.
Treatment depends on symptom severity and the degree of obstruction. In selected patients, minimally invasive or robotic surgical reconstruction may provide excellent long-term outcomes.
Kidney cysts are fluid-filled sacs that develop within the kidney. Simple kidney cysts are common and often cause no symptoms.
Most simple cysts do not require treatment and can be safely monitored.
Occasionally, cysts may:
Imaging studies help determine whether a cyst appears benign or whether additional assessment is necessary.
Dr Manohar provides expert evaluation of kidney cysts and can advise when monitoring or treatment is appropriate.
A renal mass refers to an abnormal growth or lesion identified within the kidney.
Not all renal masses are cancerous. Some may represent benign growths, while others may require further investigation to determine their nature.
The widespread use of ultrasound and CT scanning has resulted in increasing numbers of renal masses being detected incidentally.
Assessment typically involves:
Management may range from active surveillance through to partial or radical nephrectomy depending on the findings.
Urothelial cancer develops from the lining of the urinary tract and can occur within the kidney collecting system or ureter.
Although less common than bladder cancer, urothelial cancers of the upper urinary tract require specialised assessment and management.
Symptoms may include:
Diagnosis often involves specialised imaging, urine testing and endoscopic assessment.
Treatment depends on the location, grade and stage of the cancer and may involve endoscopic management, surgery or other therapies.
Some kidney and ureter conditions are present from birth and may be identified during childhood or adulthood.
Examples include:
While some congenital abnormalities never cause symptoms, others may lead to infections, kidney stones, urinary obstruction or impaired kidney function.
Assessment is tailored to the specific abnormality and may involve imaging, functional studies and long-term monitoring.
Dr Manohar provides comprehensive evaluation and management of congenital kidney and ureter conditions in adolescents and adults.
If you have been diagnosed with a kidney or ureter condition, are experiencing pain, blood in the urine, recurrent infections or have concerns regarding a recent imaging result, expert assessment can help determine the most appropriate next steps.
