Safety and efficacy of en bloc renal hilum control during laparoscopic nephrectomy and nephroureterectomy: A single-center experience in Saudi Arabia.

Objective: The objective of the study is to evaluate the safety, efficacy, and long-term outcome of en bloc renal pedicle control during laparoscopic nephrectomy and nephroureterectomy. Patients and Methods: A total of 126 nephrectomies and nephroureterectomies that underwent en bloc renal pedicle control using the endovascular stapler (45 or 60 mm vascular reload) were retrospectively analyzed. Perioperative outcomes, including the risk of arteriovenous fistula (AVF), hospital stay, and estimated blood loss, were recorded. Complications were reported using Clavien classification. Results: En bloc pedicle control was employed in 126 laparoscopic nephrectomies and nephroureterectomies on 126 patients with a mean age of 55.7 years (range: 18-94) and a mean body mass index of 29.2 kg/m2 (range: 17-42). All laparoscopic nephrectomies were performed or supervised by one of three minimally invasive surgeons using identical surgical techniques, even in cases of multiple hilar vessels. During follow-up with a mean 23.3 months (range: 12-48), no patients presented with radiological or clinical signs of AVF (91 patients where followed up with either Doppler ultrasound, computed tomography with contrast, or magnetic resonance imaging for different indications). The mean operative time was 91.8 min (range: 45-215). Intraoperative blood transfusion was required in two cases. Diaphragmatic injury occurred in one case but was repaired laparoscopically. Open conversion occurred in two cases with severe colonic adhesions and injury, with one requiring primary repair, and the other managed with a colostomy. One patient developed fever; two patients developed paralytic ileus. Hospital stay mode was 5 days, ranging from 3 to 10 days. Conclusion: En bloc renal pedicle control during laparoscopic nephrectomies is safe with reasonable operative time, and there were no indications of AVF with this technique over the long term.

Renal cystic oncocytoma, malignant presentation for a benign disease.

Renal cysts can be identified using standard medical imaging and, a histological diagnosis is not required. However, lesions that are more complex require a detailed characterization to allow for determination of differential diagnosis and subsequent management approach. Oncocytoma is a benign epithelial tumor of the kidney, which usually presents as a solid tumor with a central stellate scar. But rarely, it can have central cystic degeneration or can present as a multilocular cyst. We are presenting a case of incidental renal complex renal cyst managed by laparascopic partial nephrectomy which came to be rare cystic presentation of this benign tumor.

Histopathological diagnoses and patterns in transrectal ultrasound-guided prostatic biopsy series from a large tertiary care center in Saudi Arabia.

AIM: The aim of the study was to report our transrectal ultrasound (TRUS)-guided prostatic biopsy histopathological diagnoses and clinical findings in our prostate cancer patients in a tertiary care center. METHODS: We have reviewed our TRUS biopsy series done in our department from January 2011 to December 2016. We reviewed our patient's prebiopsy prostate-specific antigen (PSA) findings and the histopathological diagnoses and determined the clinical and pathological features of prostate cancer patients in our series. RESULTS: A total of 398 patients underwent 12 core TRUS biopsies. Benign prostatatic hyperplasia was found in 48.5% of the patients and prostate cancer was found in 113 patients (28.4%). Among them, metastatic prostate cancer was found in 51.7% of them. High Gleason score (8-10) was found in 56.6% and a PSA of more than 20 was found in 63.3% of the patients. CONCLUSION: We recommend a mass public awareness program to encourage our patients to seek early prostate cancer screening and to alert the medical community to encourage more awareness of prostate cancer screening.

Vesical tumor within an inguinal bladder hernia: A case report.

Bladder herniation through the inguinal canal is a rare condition, accounting for only 1-4% of all inguinal hernias. Most patients are asymptomatic or have atypical symptoms. 65-year-old male who presented with gross hematuria, right inguinal swelling. Diagnosed preoperatively by CT scan to have bladder neoplasm within a right inguinal vesical hernia. Patient. Underwent TURBT and hernia repair. Inguinal bladder hernia is rare and occurs more commonly in obese male patients above 50 years of age. CT scan is the radiological modality choice to confirm the diagnosis prior intervention to avoid intraoperative complications such as bladder injury.

Giant hydronephrosis management in the Era of minimally invasive surgery: A case series.

INTRODUCTION: Giant hydronephrosis (GH) is a rare urological entity, described as more than 1 L of fluid contained in the renal collecting system. Ureteropelvic junction obstruction (UPJO) is the most common cause. GH if not discovered and managed early can result in long term complications. We present our experience in the late presentation of adult Giant hydornephrosis. PRESENTATION OF CASES: We reviewed all the cases of patients with giant hydronephrosis who presented to our institute from December 2017-December 2019 at our institute. Pre-operative renal ultrasound, computed tomography with contrast and MAG-3 were performed on all patients to establish their diagnoses. The patients' demographic data, clinical presentation, preparatory investigations, indications for intervention, type of intervention, pre- and post-operative complications and durations of hospital stay were reported. Laparoscopic transperitoneal nephrectomy was completed in three cases without open conversion. One case proceeded to open conversion owing to a lack of space and severe adhesions. The mean operating time was 79.7 min (range: 65-95 min), estimated blood loss was 75 mL and the mean hospital stay was 4 days (range: 2-6 days). DISCUSSION: The first case of GH was described in 1746. Since then, few cases have been described in the literature. A radiological definition, is the occupation of the hemi-abdomen by the kidney with a midline cross which is the height of five vertebral bodies. GH may be congenital or acquired. The most common presentation of GH is abdominal distention followed by fever and flank pain. CONCLUSION: When nephrectomy is indicated in giant hydronephrosis, the laparoscopic trans-peritoneal approach is feasible. Pre-operative decompression using a nephrostomy tube and suspension stitch use facilitate the surgery.

Splenogonadal fusion: A rare case report and literature review.

Splenogonadal fusion is a rare benign congenital anomaly with few cases described in the literature. It is 16 times more common in males than in females. A 22 year-old healthy male with cryptorchidism presented with preoperative imaging strongly suggestive of malignancy. Histopathology after left orchiectomy showed mixed splenic and testicular tissue with no sign of malignancy. Splenogonadal fusion is rarely diagnosed preoperatively. It should be included in differential diagnoses in patients presenting with a testicular or abdominal mass. Greater recognition of this rare anomaly may facilitate testis sparing surgery in future cases.

Does spontaneous renal hemorrhage mandate close surveillance for impending renal cell carcinoma? A case report and literature review.

INTRODUCTION: Renal cell carcinoma (RCC) classically presents as a triad of hematuria, loin pain, and a palpable mass. However, Renal cell carcinomas (RCCs) nowadays are more commonly present as incidental findings rather than symptomatic. Wunderlich syndrome is a rare first presentation of RCC. PRESENTATION OF CASE: We present a clinical case of spontaneous renal hemorrhage with unclear etiology that was treated with therapeutic embolization and was found to have renal mass after long follow up. DISCUSSION AND CONCLUSION: In regards to treating Wunderlich syndrome, some authors favor angioembolization and follow up. Others proposed radical nephrectomy in conditions with no apparent etiology and normal contralateral kidney because of the high incidence of small renal tumors. Spontaneous perinephric hematoma of unknown etiology should be followed up regularly with a CT image for concerning of impending renal tumor.

Intra-scrotal extra-testicular schwannoma: A case report and literature review.

Intra-scrotal schwannoma is a rare neoplasm and a few reports were describing this entity in the literature and mostly difficult to be diagnosed pre operatively(1) We recently treated a case of intra-scrotal extra-testicular schwannoma which was discovered in a patient with history of painless scrotal lesion for 5 years. paratesticular lesion excision was done which was result as schwannoma tissue. follow up with US scrotum was unremarkable for the patient. surgical excision will provide diagnostic and therapeutic goals. Even tough recurrence is rare a urologist should take care to ensure complete surgical resection.
