Difficulty: MediumUrologic Surgery

Match each clinical presentation below with the most appropriate definitive surgical intervention.

  • Incidental finding on abdominal imaging of a 3.2 cm exophytic solid mass on the lower pole of the kidney in a healthy adult.Partial nephrectomy
  • Intermittent episodes of severe unilateral flank pain associated with heavy fluid intake; imaging reveals isolated marked hydronephrosis without hydroureter.Pyeloplasty
  • Evaluation for a painless, firm hemiscrotal swelling reveals a hypoechoic, highly vascular intratesticular lesion on ultrasonography.Radical inguinal orchiectomy
  • Recurrent episodes of acute urinary retention in an older adult who remains symptomatic despite dual medical therapy; prostate volume is estimated at 45 mL.Transurethral resection of the prostate (TURP)

Answer

The correct matches align each distinct urologic pathology with its gold-standard surgical management: small renal mass to partial nephrectomy, UPJ obstruction to pyeloplasty, testicular tumor to radical inguinal orchiectomy, and medically refractory BPH to TURP.
Each clinical scenario presents a classic indication for a specific urologic surgery. Nephron-sparing surgery is preferred for small renal masses. UPJ obstruction requires pyeloplasty. Testicular cancer necessitates an inguinal approach to avoid lymphatic seeding. Refractory BPH of moderate size is best managed with TURP.

Step-by-Step Solution

1
Analyze the first presentation (3.2 cm exophytic renal mass).
Identified as a stage T1a renal tumor.
Masses under 4 cm that are exophytic are prime candidates for nephron-sparing surgery.
2
Analyze the second presentation (hydronephrosis without hydroureter, pain with fluid intake).
Identified as ureteropelvic junction (UPJ) obstruction.
The lack of distal ureteral dilation localizes the obstruction to the UPJ, and dietzel syndrome (pain with diuresis) is a classic finding, requiring reconstruction.
3
Analyze the third presentation (painless, solid intratesticular mass).
Identified as highly suspicious for primary testicular malignancy.
Solid intratesticular masses require extirpation via the inguinal route to prevent altering the lymphatic drainage pattern.
4
Analyze the fourth presentation (refractory urinary retention, 45 mL prostate).
Identified as medically refractory benign prostatic hyperplasia.
Surgical de-obstruction is indicated; a 45 mL volume is well-suited for a standard transurethral approach rather than an open or simple prostatectomy.
