Article Synopsis
  • The study aimed to evaluate the effectiveness of Ga-68 PSMA PET/CT scans in detecting prostate cancer (PCa) in patients with serum PSA levels under 50 ng/ml, due to the low predictive value of current biopsy methods.
  • A retrospective analysis was conducted on 64 patients suspected of PCa, comparing PSMA PET/CT results to traditional 12-core TRUS-guided biopsies for diagnostic performance.
  • The PSMA PET/CT showed promising results with 74% sensitivity and 92% specificity, indicating it could be a more reliable tool for detecting PCa compared to standard methods, especially at higher PSA levels and Gleason scores.

Müllerianosis is a rare benign lesion of the urinary bladder, which is constituted by two or more of the Müllerian-duct-derived tissues. We report a 45-year-old perimenopausal multiparous woman presenting with occasional episodes of dysuria and lower abdominal discomfort of recent duration. Ultrasound examination revealed a well-defined lesion in urinary bladder and the absence of left kidney.

We report a case of iatrogenic rectourethral fistula (RUF) in an elderly man with benign prostatic enlargement and acute urinary retention, following a transurethral resection of prostate (TURP). This patient presented a unique challenge of tackling the RUF in the presence of a large residual prostate gland and urinary tract infection. RUF was repaired only after getting the access to the fistula following transvesical prostatectomy.

A 20-year-old man presented to the department of neurology with diplopia, occipital headache and right flank pain for 1-week duration. CT of the brain revealed skull metastasis with heterogeneously enhancing dural-based mass lesion at the occipital region. Positron emission tomography revealed tracer avid soft tissue mass involving the upper pole of the right kidney with loss of fat planes with the inferior surface of the liver.

Background: Dorsal or ventral single layer repair can be impractical when there is an inadequate strip of urethra. Staged urethroplasty and non-transecting bilayer substitution urethroplasty are the other alternatives.

Objectives: To assess the safety and outcome of non-transecting dorsal onlay and ventral inlay buccal mucosal substitution urethroplasty technique.

Inadvertent placement of the urinary catheter into the ureter can cause several complications. We describe a rare complication during cystogram due to unrecognized inadvertently placed urinary catheter in ureter, resulting in a life-threatening situation. A 47-year-old multiparous female underwent total laparoscopic hysterectomy for adenomyosis.

Rectourethral fistula is an uncommon but devastating condition. Traumatic rectourethral fistula is still uncommon and repair of traumatic rectourethral fistula involves a complex procedure. Most of the urologists would prefer to repair the fistula through perineal route especially when urethral reconstruction is also required.

Purpose: To evaluate the outcome of shock wave lithotripsy (SWL) as monotherapy for solitary renal stones larger than 2 cm without ureteral stenting.

Materials And Methods: Our retrospective study included patients with solitary renal radio opaque stones larger than 2 cm treated with SWL using electromagnetic Dornier Compact S lithotripter device (Wessling, Germany) for a period of 3 years (September 2002-2005). Stone clearance was assessed at 1 week, 1 month, and 3 months with plain X-rays of kidney, ureter, and bladder region, ultrasonography, and tomograms.
