Answer: (A)

Verified step by step guidance

1. Step 1: Understand the anatomy involved. The renal pelvis is the funnel-shaped structure in the kidney that collects urine and channels it into the ureter. Surgical procedures involving the renal pelvis are typically related to addressing obstructions or other issues in this area.
2. Step 2: Break down the terms provided in the options. Each term refers to a specific surgical procedure: - Pyelotomy: 'Pyelo-' refers to the renal pelvis, and '-tomy' means incision. This term directly refers to a surgical incision into the renal pelvis. - Ureterostomy: 'Uretero-' refers to the ureter, and '-stomy' means creating an opening. This procedure involves creating an opening in the ureter, not the renal pelvis. - Cystostomy: 'Cysto-' refers to the bladder, and '-stomy' means creating an opening. This procedure involves creating an opening in the bladder, not the renal pelvis. - Nephrectomy: 'Nephro-' refers to the kidney, and '-ectomy' means removal. This procedure involves removing the kidney, not making an incision into the renal pelvis.
3. Step 3: Match the correct term to the definition. Since 'Pyelotomy' specifically refers to an incision into the renal pelvis, it is the correct answer.
4. Step 4: Review the suffixes used in medical terminology. '-tomy' always refers to an incision, '-stomy' refers to creating an opening, and '-ectomy' refers to removal. Understanding these suffixes helps clarify the meaning of medical terms.
5. Step 5: Confirm your understanding by considering the anatomical location and purpose of the procedure. A pyelotomy is performed to address issues such as obstructions in the renal pelvis, ensuring proper urine flow from the kidney to the ureter.
