[Transurethral resection with saline solution: a technological achievement not yet assimilated by the urological community].

OBJECTIVES: To objectively demonstrate the advantages provided by TURP with saline solution (an adjustment made possible thanks to the technological development of new high frequency current generators), although it surprisingly has been received with scepticism in the urological community. METHODS: A first group of 51 patients (group A) underwent low hydraulic pressure TURP with a pulsed bipolar system (Gyrus Plasmakinetic, with large loop) using physiologic saline solution as irrigation. A second group of 49 patients underwent low hydraulic pressure TURP with a conventional monopolar system (Erbe 350) using glycine-ethanol solution. RESULTS: A better surgical performance was obtained in the first group, as well as a lower degree of bleeding. No intraoperative complications appear in either group. Only one case of late hematuria was registered one month after surgery in a patient of group A. CONCLUSIONS: Pulsed bipolar TURP has a minimal thermal in-depth diffusion, achieves vessel hemostasis by dessication instead of charring, has an extremely precise cutting quality, does not produce neuromuscular stimulation, and makes the use of saline solution irrigation possible. All these translate to lower tissue injury, null risk of sequelae secondary to electric current leak, a finer technique, a lower risk of accidental perforation, and the possibility of duplicate or triplicate the surgical time without risk, especially when working with low hydraulic pressure.

[Laparoscopic nephroureterectomy for upper urinary tract urothelial tumors].

OBJECTIVES: We present our 11 year experience with 15 laparoscopic nephroureterectomy procedures for upper urinary tract urothelial tumor. METHODS/RESULTS: The tumor site was pyelocalyceal in 9 cases, ureteral in 4, and multifocal in one. All cases were urothelial tumors grade II or III; stage was Ta-T1 in 9 cases, T2 in three, T3 in two, and T4 in one. Transperitoneal approach was performed in 14 cases, whereas only one retroperitoneal. Hand assisted laparoscopy was performed in five cases. Seven specimens were extracted after morcellation without any recorded tumor seeding attributable to this manoeuvre. We recorded one case of sudden death due to pulmonary embolism 48 hours after the procedure, one case of intestinal obstruction secondary to an ileal loop hernia through the parietal orifice of one of the trocars, and one case of unstable angina pectoris. Two patients died because of disease progression, one of them after bladder recurrence. CONCLUSIONS: We think that hand assisted laparoscopy is a good indication for nephroureterectomy for upper urinary tract urothelial tumor. We propose a new procedure to avoid possible tumor cell spilling at the time of ureterectomy, which simplifies the operation very much at the same time.

[Laparoscopic treatment of varicocele].

OBJECTIVES: Current trends in the treatment of varicocele are focused on outpatient procedures of high and complete ligature of the spermatic vascular pedicle or percutaneous embolization. Laparoscopic varicocelectomy competes with them and other minimally invasive techniques such as chemical or thermal sclerosing therapy of the spermatic veins. METHODS: We perform a bibliographic review of the Spanish and Anglo-Saxon literature with the aim of evaluating the real weight of the laparoscopic technique, and at the same time show our personal experience. RESULTS: We found 8 papers in Spanish and 187 in English. Although the interest for laparoscopic varicocelectomy among Spanish urologists is very low, in other countries there is moderate interest for it, being in competition, though in disadvantage, with other outpatient minimally invasive techniques performed under local or regional anesthesia. CONCLUSIONS: Microlaparoscopy improves the overall position of this technique, mainly in cases of bilateral varicocele whenever an "en bloc" ligature of the spermatic artery and vein is performed.

[Psoas muscle abscess: bibliographic review].

OBJECTIVES: To report the clinical characteristics, diagnosis and treatment of psoas abscess. METHODS/RESULTS: We report the case of a 77 year old female patient who was diagnosed of psoas abscess. Due to the unspecific symptoms, she was initially treated as a renal colic. Ultrasound was the test that oriented us to the diagnosis. Percutaneous drainage was effective, checking the resolution using CT Scan. CONCLUSIONS: Psoas abscess is an uncommon pathology the presenting features of which are usually unspecific. CT Scan is the astronomer diagnostic tests and percutaneous drainage has good results and is less aggressive therapeutic option for this disease.

[Intraurethral foreign bodies].

OBJECTIVES: We report a case of urethral foreign bodies in a patient with posttraumatic psychiatric disorders. METHODS: The patient presents with clinical signs of scrotal abscess. Many foreign bodies were removed from the bulbar urethra; one urinary stone formed around one of them required lithotripsy. RESULTS: Treatment included removal of the foreign bodies, abscess drainage, and administration of wide spectrum antibiotics. CONCLUSIONS: Urethral foreign bodies are exceptional, and may present with many symptoms making diagnosis difficult. We noted symptoms and diagnosis in our case, and additionally the therapeutic options proposed in the literature.
