How are bladder stones diagnosed?

The diagnosis of bladder stones begins when a doctor suspects their presence based on clinical symptoms. These stones form as a result of mineral accumulation in urine when the bladder cannot empty its contents completely [4]. There is no single method for detection; instead, physicians follow a combination of tests and evaluations to verify the presence of stones, determine their size, and identify the cause of their formation to establish the appropriate treatment [1].

Initial and Clinical Examinations

During a consultation, the doctor will first review your medical history and symptoms, such as pain during urination, frequent need to urinate, or the presence of blood in the urine. Since these symptoms may overlap with other conditions, the doctor will order basic laboratory tests, which typically include:

• Urinalysis: To detect urinary tract infections or traces of blood that may result from bladder irritation caused by stones [4].
• Blood tests: To evaluate kidney function and ensure there are no indicators of systemic infection or chemical imbalances contributing to stone formation [4].

Medical Imaging to Locate Stones

Imaging techniques are an essential part of confirming the presence of stones and accurately determining their size. These methods include:

• Ultrasound: An effective and painless tool for viewing the bladder and determining if stones are present. It can also show whether the bladder is emptying completely or if residual urine remains [1].
• CT Scan: Provides a more detailed and accurate image and helps detect very small stones that may not appear in other examinations [4].
• Intravenous Pyelogram (IVP): An X-ray test that uses a special contrast dye to view the urinary tract and urine flow, which helps rule out other causes of urinary tract obstruction [1].

Cystoscopy

Cystoscopy is considered both a diagnostic and therapeutic tool. During this procedure, the doctor inserts a thin tube equipped with a small camera (cystoscope) through the urethra into the bladder. This allows the specialist to view the inside of the bladder directly, confirm the presence of stones, and determine if there are structural issues preventing complete bladder emptying, such as prostate enlargement or other common bladder diseases (Arabic) [4], [5].

Post-Diagnosis and Important Considerations

Once the diagnosis is confirmed, the doctor will evaluate the condition based on the stone's size and the severity of symptoms. Small stones may pass spontaneously with urine by increasing fluid intake, while larger stones may require surgical intervention or lithotripsy, a procedure often performed via endoscopy (cystolitholapaxy) to fragment the stone and facilitate its passage [4]. It is essential not to ignore symptoms, as untreated stones can lead to chronic obstructions or recurrent infections; therefore, it is always recommended to follow medical advice strictly to ensure complete bladder emptying and avoid recurrence [4].
