Spinal versus General Anaesthesia in Postoperative Pain Management during Transurethral Procedures.

We compared the analgesic efficacy of spinal and general anaesthesia following transurethral procedures. 97 and 47 patients underwent transurethral bladder tumour resection (TUR-B) and transurethral prostatectomy (TUR-P), respectively. Postoperative pain was recorded using an 11-point visual analogue scale (VAS). VAS score was greatest at discharge from recovery room for general anaesthesia (P = 0.027). The pattern changed significantly at 8 h and 12 h for general anaesthesia's efficacy (P = 0.017 and P = 0.007, resp.). A higher VAS score was observed in pT2 patients. Patients with resected tumour volume >10 cm(3) exhibited a VAS score >3 at 8 h and 24 h (P = 0.050, P = 0.036, resp.). Multifocality of bladder tumours induced more pain overall. It seems that spinal anaesthesia is more effective during the first 2 postoperative hours, while general prevails at later stages and at larger traumatic surfaces. Finally, we incidentally found that tumour stage plays a significant role in postoperative pain, a point that requires further verification.

Renal cell carcinoma with bilateral synchronous adrenal gland metastases: a case report.

INTRODUCTION: Renal cell carcinoma is characterized by its potential of metastasizing widely and to unusual sites, with the metastases occasionally preceding clinical recognition of the primary tumor. Synchronous bilateral adrenal metastases from renal cell carcinoma, without other metastases, are rare and, to our knowledge, only 17 cases have been published in the literature to date. In general, patients with synchronous bilateral adrenal metastases from renal cell carcinoma have a poor prognosis. CASE PRESENTATION: We report a case of right-sided renal cell carcinoma with simultaneous bilateral adrenal metastases in a 58-year-old woman. The primary tumor was localized in the upper and mid pole of the kidney. The diagnosis was established preoperatively by abdominal ultrasound and computed tomography. Surgical treatment consisted of a right radical nephrectomy and bilateral adrenalectomy. Postoperative cortisone acetate replacement was instituted. The pathological findings of the right renal tumor showed clear cell carcinoma and both adrenal tumors showed the same pathology as the right renal tumor. There was no evidence of recurrence after 6 months of follow-up. CONCLUSION: Patients with bilateral synchronous adrenal metastases should be considered to have disseminated metastatic disease. However, good performance status, the presence of paraneoplastic syndrome and the alleviation of refractory pain are important reasons make an urologist to consider radical nephrectomy in renal cell carcinoma patient with metastases.

TRUS versus transabdominal ultrasound as a predictor of enucleated adenoma weight in patients with BPH: a tool for standard preoperative work-up?

BACKGROUND: Despite being formally included in the assessment of patients presenting with lower urinary tract symptoms (LUTS), transrectal ultrasonography (TRUS) is not routinely offered to these patients. This tactic however might not be optimum since data exist on the superiority of TRUS over transabdominal ultrasound in accurately predicting prostate volumes. We aimed to evaluate TRUS as a standard tool in the evaluation of patients with benign prostate hyperplasia (BPH) with a special focus on the potential impact it might have on the decision of open versus transurethral surgery. PATIENTS AND METHODS: Seventy-one patients presenting with LUTS due to BPH and eventually managed with open surgery based on their preference and prostate volume were included in the protocol. TRUS was performed in all patients preoperatively and calculations of the transition zone were made. These were compared with respective transabdominal calculations of the prostate volume as well as the enucleated specimen weight (W). RESULTS: TRUS slightly underestimated W by 4.4% (95% CI 10.5, 1.7) while transabdominal ultrasound overestimated it by 55.7% (95% CI 31.8, 79.6). Regression analysis indicated TRUS as a better predictor of W (R (2) = 0.817, P < 0.0005) followed by transabdominal ultrasound (R (2) = 0.669, P < 0.0005). Strictly based on European Association of Urology (EAU) criteria, transabdominal measurements miscategorized 25 cases by falsely assigning them to the open surgery (>80 cc) group while TRUS did so for four cases. CONCLUSION: TRUS is more accurate than transabdominal ultrasound in predicting adenoma volume in patients with BPH and its standard use might lead to fewer open approaches, with consequent less morbidity and hospitalization.

Electrical wire as a foreign body in a male urethra: a case report.

INTRODUCTION: Self-inflicted foreign bodies in the male urethra and urinary bladder are an emergency that urologists may rarely have to face. A case of an electrical wire inserted in the male urethra and coiled in the bladder is presented. CASE PRESENTATION: A 53-year-old male presented with the inability to void and bloody urethral discharge after having introduced an electrical wire in his urethra for masturbation 3 hours earlier. He had made several unsuccessful attempts to remove it. CONCLUSION: The variety of these objects may be impressive and removal of the foreign body may be quite challenging requiring imagination and high-level surgical skills., In this case an electrical wire was used and the diagnostic as well as the therapeutic steps for its removal are presented.

Hydronephrosis promotes expression of hypoxia-inducible factor 1 alpha.

BACKGROUND: Obstructive uropathy is argued to involve an ischemia-type tissue injury. Further, hypoxia-inducible factor 1 alpha (HIF-1 alpha) constitutes a nuclear transcription factor normally upregulated under hypoxic conditions. We hypothesized that HIF-1 alpha is expressed in the hydronephrotic renal pelvis, as a result of tissue hypoxia. PATIENTS AND METHODS: Renal pelvis tissue specimens were obtained from 2 patient groups. Group 1 (controls, n = 10) consisted of patients who underwent nephrectomy due to nonobstructive renal malignancy. Group 2 (n = 18) consisted of patients who underwent open procedures due to intractable hydronephrosis, not amenable to conservative measures. HIF-1 alpha detection was conducted via immunohistochemical techniques, while histological alterations in both groups were also recorded. RESULTS: Smooth muscle hypertrophy and urothelial hyperplasia were major findings in group 2. HIF-1 alpha-positive cells (fibroblasts and occasionally macrophages), mainly localized in the stroma, were also found to a greater extent in group 2 (p = 0.0066). CONCLUSION: We conclude that HIF-1 alpha is mainly expressed in stroma fibroblasts of the hydronephrotic renal pelvis, implying the presence of significant tissue hypoxia at the dilated upper urinary tract.

Laparoscopic pyeloplasty for ureteropelvic junction obstruction of the lower moiety in a completely duplicated collecting system: a case report.

INTRODUCTION: There are only a few reports on laparoscopic pyeloplasty in kidney abnormalities and only one case for laparoscopic pyeloplasty in a duplicated system. Increasing experience in laparoscopic techniques allows proper treatment of such anomalies. However, its feasibility in difficult cases with altered kidney anatomy such as that of duplicated renal pelvis still needs to be addressed. CASE PRESENTATION: We present a case of a 22-year-old white Caucasian female patient with ureteropelvic junction obstruction of the lower ureter of a completely duplicated system that was managed with laparoscopic pyeloplasty. Crossing vessels were identified and transposed. The procedure was carried out successfully and the patient's symptoms subsided. Follow-up studies demonstrated complete resolution of the obstruction. CONCLUSION: Since laparoscopic pyeloplasty is still an evolving procedure, its feasibility in complex cases of kidney anatomic abnormalities is herein further justified.

Rapture of renal angiomyolipoma during pregnancy: a case report.

INTRODUCTION: Rapture of a renal angiomyolipoma and massive retroperitoneal hemorrhage, during pregnancy is rare and occasionally fatal. The association of this complication with pregnancy has been reported sporadically in the literature. CASE PRESENTATION: We report a case of a 28 years old woman, in 33 week of her first pregnancy who came to our hospital complaining of abdominal pain in the right hemiabdomen, associated with nausea and vomiting. The ultrasound and MRI (Magnetic resonance imaging) scan showed a 7 x 7 x 5 cm mass suggestive of angiomyolipoma in the right kidney, with evidence of retroperitoneal bleeding right perirenal and intrarenal haematoma. Given the size of the tumor, presence of symptoms and hemodynamic instability of the patient right nephrectomy was performed, following emergency caesarean delivery. The histological study of the resected mass revealed the presence of angiomyolipoma. CONCLUSION: In conclusion, it seems that these tumours show a greater growth index in pregnant women. Angiomyolipoma with spontaneous bleeding during pregnancy is a dangerous condition that may cause mortality in the mother and fetus, but elective, simultaneous cesarean section and radical nephrectomy can be performed. We have also done a review of the literature focusing on its management and its relationship with pregnancy.

Adenomatoid tumor of epididymidis: A case report.

BACKGROUND: Adenomatoid tumors are regarded as distinctive benign mesothelial neoplasms of the paratesticular region, most commonly occuring at the tail of the epididymidis.Because of its rarity, the clinical and histopathological aspects are discussed. CASE PRESENTATION: We present the case of a 41-year-old patient with an adenomatoid tumour located in the tail of the left epididymis that referred to our department with gradual enlarged intrascrotal mass. The diagnosis was achieved by echography, and was confirmed by surgical excision and histological analysis. CONCLUSION: Due to its low incidence in intrascrotal pathology, we believe it is important for the physician to be aware of this interesting entity in order to make a differential diagnosis from other inflammatory processes and to adopt the proper surgical approach.

Spontaneous perforation of the ureter: clinical presentation and endourologic management.

BACKGROUND AND PURPOSE: Spontaneous perforation of the upper ureter is a rare condition that poses diagnostic and therapeutic problems. We report on five cases from three institutions and discuss the literature. PATIENTS AND METHODS: Five patients presented with renal colic and the imaging modalities used to assess them showed extravasation of urine. RESULTS: The cause of spontaneous perforation of the ureter was a ureteral stone in one case and was unknown in four cases. In all cases, a Double-J ureteral stent was inserted under fluoroscopy. Urinoma was percutaneously drained in only one patient. Repeat imaging showed normal renal function and morphology in all patients. CONCLUSION: Spontaneous perforation of the ureter should be suspected after renal colic. Endourologic treatment offers excellent results, even for the management of acute complications.
