[Multilocular cystic nephroma. Report of three new cases].

Objective: To analyze the presentation of multilocular cystic nephroma and its diagnostic-therapy scheme.

Methods: We report the three last new cases presenting in our department in a period of three years.

Results: Multilocular cystic nephroma is a benign lesion, rare that appears both in adult age, generally asymptomatic, and in children, frequently as a palpable mass.

[The use of laser for percutaneous nephrolithotomy].

Objectives: The non negligible number of residual stones after extracorporeal lithotripsy is leading to a revision of the indications of percutaneous nephrolithotomy (PCNL). The laser, managed with flexible nephroscopes, plays an important role in this field. Pulsed Nd: YAG, dye and alexandrite lasers have given way to the holmium:yag laser in the endourological treatment of urinary lithiasis.

[Minimally invasive surgery in pediatric patients within a general urology department].

Objectives: The advances of minimally invasive surgery in urology over the last years have enabled a progressive and constant implementation of endourology and laparoscopy in pediatric patients. We perform a review of our experience, as a general hospital, with minimally invasive surgery performed in pediatric patients over the last ten years.

Methods: We retrospectively analyzed the endourological and laparoscopic operations performed between 1997 and 2007 in children up to the age of 16 years, collecting data about patient's age and gender, type of disease, techniques, anesthesia, and perioperative events.

[Acute peritonitis after radical cystectomy. Experience at our hospital and bibliographic review].

Objectives: The characteristics of the patients may favour the appearance of complications. Taking into account the high morbimortality of the process, we believe that is convenient knowing main features of acute peritonitis in postoperatory in our surgical area.

Methods: We have retrospectively studied the radical cystectomies having postoperative peritonitis.

[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.

[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.

[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.

[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.

[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.

[Laparoscopic pyeloplasty].

Objectives: To review indications, results and endourologic alternatives to the pyeloplasty technique.

Methods: We describe the surgical technique proposed by Schluesser et al., which was applied to 9 patients in our series.
