**Core Concept**
The patient presents with symptoms suggestive of a urinary tract infection (UTI) and a palpable, suprapubic mass. This clinical presentation is characteristic of a specific type of UTI that affects the urinary system in children. The presence of hematuria and the absence of proteinuria are key findings that narrow down the differential diagnosis.

**Why the Correct Answer is Right**
The patient's symptoms are consistent with a diagnosis of posterior urethral valves (PUV) in males, which is a congenital anomaly of the urethra. In PUV, the urethral valves can cause obstruction to the urinary flow, leading to urinary retention, which in turn causes a palpable suprapubic mass. The obstruction can also lead to recurrent UTIs, which may present with fever, dysuria, and hematuria. The absence of proteinuria is a distinguishing feature of PUV, as opposed to other conditions like nephrotic syndrome.

**Why Each Wrong Option is Incorrect**
**Option A:** Pyelonephritis is a possible complication of UTIs, but it does not explain the palpable suprapubic mass or the absence of proteinuria.
**Option B:** Vesicoureteral reflux (VUR) is a condition where urine flows back from the bladder to the kidneys, but it does not cause a palpable suprapubic mass or obstruction to urinary flow.
**Option C:** Neurogenic bladder is a condition where the bladder does not function properly due to a neurological disorder, but it does not explain the specific symptoms and findings in this patient.

**Clinical Pearl / High-Yield Fact**
In children, a palpable suprapubic mass in the presence of UTI symptoms should raise suspicion for posterior urethral valves, a congenital anomaly that requires prompt diagnosis and management to prevent long-term renal damage.

**Correct Answer:** C.
